Technical Interview Questions with Answers

Q1: Write a program to check if a number is Armstrong.

public class ArmstrongNumber {
    // Check if number is Armstrong
    public static boolean isArmstrong(int number) {
        int originalNumber = number;
        int sum = 0;
        int digits = String.valueOf(number).length();
        
        while (number > 0) {
            int digit = number % 10;
            sum += Math.pow(digit, digits);
            number /= 10;
        }
        
        return sum == originalNumber;
    }
    
    // Alternative without converting to string
    public static boolean isArmstrongV2(int number) {
        int originalNumber = number;
        int sum = 0;
        int temp = number;
        int digits = 0;
        
        // Count digits
        while (temp > 0) {
            digits++;
            temp /= 10;
        }
        
        temp = number;
        // Calculate sum of digits raised to power
        while (temp > 0) {
            int digit = temp % 10;
            int power = 1;
            for (int i = 0; i < digits; i++) {
                power *= digit;
            }
            sum += power;
            temp /= 10;
        }
        
        return sum == originalNumber;
    }
    
    public static void main(String[] args) {
        System.out.println(isArmstrong(153));  // true (1³ + 5³ + 3³ = 153)
        System.out.println(isArmstrong(370));  // true
        System.out.println(isArmstrong(123));  // false
    }
}

Armstrong Number: A number equal to the sum of its digits raised to the power of number of digits. Examples: 153 (1³+5³+3³=153), 370, 371, 407

Q2: What is the difference between C and Java?

Key Differences:

C is compiled directly to machine code; Java compiles to bytecode run by JVM
C requires manual malloc/free; Java has automatic garbage collection
C allows direct memory manipulation; Java provides memory safety
C is better for low-level programming; Java excels in enterprise applications

Similarities: Both have similar syntax, support functions, loops, and conditional statements."

Q3: Write a SQL query to find duplicate email addresses.

-- Find duplicates with count
SELECT email, COUNT(*) as occurrence
FROM users
GROUP BY email
HAVING COUNT(*) > 1;

-- Find all records that have duplicates
SELECT u1.*
FROM users u1
JOIN (
    SELECT email
    FROM users
    GROUP BY email
    HAVING COUNT(*) > 1
) u2 ON u1.email = u2.email
ORDER BY u1.email;

-- Delete duplicates keeping one (MySQL)
DELETE u1 FROM users u1
JOIN users u2 
WHERE u1.id > u2.id AND u1.email = u2.email;

-- Using ROW_NUMBER to identify duplicates (Standard SQL)
WITH RankedUsers AS (
    SELECT *,
        ROW_NUMBER() OVER (PARTITION BY email ORDER BY id) as rn
    FROM users
)
SELECT * FROM RankedUsers WHERE rn > 1;

-- Delete using ROW_NUMBER
WITH RankedUsers AS (
    SELECT *,
        ROW_NUMBER() OVER (PARTITION BY email ORDER BY id) as rn
    FROM users
)
DELETE FROM users WHERE id IN (
    SELECT id FROM RankedUsers WHERE rn > 1
);

HAVING clause filters groups after aggregation, unlike WHERE which filters rows before aggregation.

Q4: Explain the difference between while and do-while loops.

while (condition) {
    // Body executes only if condition is true
    // May execute zero or more times
}

// Example
int i = 0;
while (i < 5) {
    System.out.println(i);
    i++;
}

do-while loop: Executes body first, then checks condition.

do {
    // Body executes at least once
    // Then checks condition
} while (condition);

// Example
int i = 0;
do {
    System.out.println(i);
    i++;
} while (i < 5);

Key Differences:

Feature	while	do-while
Condition Check	Before execution	After execution
Minimum Executions	0	1
Use Case	When execution is conditional	When at least one execution required
Syntax	while (condition) { }	do { } while (condition);
Semicolon	No semicolon after while	Semicolon required after while

When to use do-while: Menu systems, input validation where you need at least one prompt.

// Input validation example
do {
    System.out.print("Enter positive number: ");
    num = scanner.nextInt();
} while (num <= 0);

Best Practice: Use while when zero iterations are possible; use do-while when at least one iteration is required."

Q5: Write a program to find the GCD (Greatest Common Divisor) of two numbers.

public class GCD {
    // Euclidean algorithm - iterative
    public static int gcdIterative(int a, int b) {
        a = Math.abs(a);
        b = Math.abs(b);
        
        while (b != 0) {
            int temp = b;
            b = a % b;
            a = temp;
        }
        return a;
    }
    
    // Euclidean algorithm - recursive
    public static int gcdRecursive(int a, int b) {
        a = Math.abs(a);
        b = Math.abs(b);
        
        if (b == 0) {
            return a;
        }
        return gcdRecursive(b, a % b);
    }
    
    // Using Java's built-in method (Java 18+)
    public static int gcdBuiltIn(int a, int b) {
        return java.math.BigInteger.valueOf(a)
            .gcd(java.math.BigInteger.valueOf(b))
            .intValue();
    }
    
    // LCM using GCD
    public static int lcm(int a, int b) {
        return Math.abs(a * b) / gcdIterative(a, b);
    }
    
    public static void main(String[] args) {
        int a = 48, b = 18;
        System.out.println("GCD of " + a + " and " + b + " is: " + 
                          gcdIterative(a, b)); // 6
        System.out.println("LCM is: " + lcm(a, b)); // 144
    }
}

Euclidean Algorithm: GCD(a, b) = GCD(b, a mod b), until b becomes 0.

Time Complexity: O(log(min(a, b))) Space Complexity: O(1) iterative, O(log(min(a, b))) recursive

Q6: What is the difference between break and continue statements?

for (int i = 0; i < 10; i++) {
    if (i == 5) {
        break; // Exit loop completely
    }
    System.out.print(i + " "); // Prints: 0 1 2 3 4
}

continue: Skips current iteration and moves to next.

for (int i = 0; i < 10; i++) {
    if (i % 2 == 0) {
        continue; // Skip even numbers
    }
    System.out.print(i + " "); // Prints: 1 3 5 7 9
}

Labeled break (for nested loops):

outer: for (int i = 0; i < 3; i++) {
    for (int j = 0; j < 3; j++) {
        if (i == 1 && j == 1) {
            break outer; // Breaks outer loop
        }
        System.out.println(i + "," + j);
    }
}

Comparison:

Aspect	break	continue
Action	Exit loop/switch	Skip to next iteration
Loop Execution	Stops completely	Continues with next iteration
Use in switch	Yes	No
Labeled	Yes (for nested)	Yes (for nested)

Best Practice: Use sparingly; they can make code harder to follow if overused."

Q7: Write a program to find the sum of digits of a number.

public class SumOfDigits {
    // Iterative approach
    public static int sumOfDigits(int number) {
        number = Math.abs(number); // Handle negative numbers
        int sum = 0;
        
        while (number > 0) {
            sum += number % 10;  // Get last digit
            number /= 10;        // Remove last digit
        }
        
        return sum;
    }
    
    // Recursive approach
    public static int sumOfDigitsRecursive(int number) {
        number = Math.abs(number);
        
        if (number == 0) {
            return 0;
        }
        
        return (number % 10) + sumOfDigitsRecursive(number / 10);
    }
    
    // Sum until single digit (digital root)
    public static int digitalRoot(int number) {
        if (number == 0) return 0;
        if (number % 9 == 0) return 9;
        return number % 9;
    }
    
    public static void main(String[] args) {
        int num = 12345;
        System.out.println("Sum of digits of " + num + ": " + 
                          sumOfDigits(num)); // 15
        System.out.println("Digital root: " + digitalRoot(num)); // 6
    }
}

Digital Root: Single digit obtained by repeatedly summing digits until one digit remains. Formula: 1 + (n - 1) % 9 for non-zero numbers.

Time Complexity: O(log n) - number of digits Space Complexity: O(1) iterative, O(log n) recursive

Q8: Explain the difference between call by value and call by reference.

Changes to parameter don't affect original variable
Used by Java for primitive types

void modify(int x) {
    x = 100; // Modifies copy only
}

int a = 50;
modify(a);
System.out.println(a); // Still 50

Call by Reference: Passes the memory address of the variable.

Changes to parameter affect original variable
Java doesn't support true call by reference
Java uses call by value for object references (reference value is copied)

void modifyObject(Person p) {
    p.name = "New Name"; // Modifies object (same reference)
}

void reassign(Person p) {
    p = new Person(); // Reassigns local copy only
}

Person person = new Person("John");
modifyObject(person); // Changes person's name
reassign(person);     // No effect on original reference

Java's Approach: Java is strictly call by value:

For primitives: value is copied
For objects: reference value is copied (object itself is not)

Key Point: In Java, you cannot write a method that swaps two integers because the method receives copies. But you can modify object's internal state because both references point to same object."

Q9: Write a program to print a pattern (pyramid).

public class PatternPrinting {
    // Pyramid pattern
    public static void printPyramid(int n) {
        for (int i = 1; i <= n; i++) {
            // Print spaces
            for (int j = 1; j <= n - i; j++) {
                System.out.print(" ");
            }
            // Print stars
            for (int k = 1; k <= 2 * i - 1; k++) {
                System.out.print("*");
            }
            System.out.println();
        }
    }
    
    // Number pyramid
    public static void printNumberPyramid(int n) {
        for (int i = 1; i <= n; i++) {
            for (int j = 1; j <= n - i; j++) {
                System.out.print(" ");
            }
            for (int k = 1; k <= i; k++) {
                System.out.print(k + " ");
            }
            System.out.println();
        }
    }
    
    // Inverted pyramid
    public static void printInvertedPyramid(int n) {
        for (int i = n; i >= 1; i--) {
            for (int j = 1; j <= n - i; j++) {
                System.out.print(" ");
            }
            for (int k = 1; k <= 2 * i - 1; k++) {
                System.out.print("*");
            }
            System.out.println();
        }
    }
    
    // Diamond pattern
    public static void printDiamond(int n) {
        // Upper half
        for (int i = 1; i <= n; i++) {
            for (int j = 1; j <= n - i; j++) System.out.print(" ");
            for (int k = 1; k <= 2 * i - 1; k++) System.out.print("*");
            System.out.println();
        }
        // Lower half
        for (int i = n - 1; i >= 1; i--) {
            for (int j = 1; j <= n - i; j++) System.out.print(" ");
            for (int k = 1; k <= 2 * i - 1; k++) System.out.print("*");
            System.out.println();
        }
    }
    
    public static void main(String[] args) {
        System.out.println("Pyramid:");
        printPyramid(5);
        
        System.out.println("\nNumber Pyramid:");
        printNumberPyramid(5);
    }
}

Pattern Logic: Use nested loops - outer loop for rows, inner loops for spaces and characters. Calculate pattern based on row number.

Q10: What is the difference between static and non-static methods?

class MathUtils {
    static int add(int a, int b) {
        return a + b;
    }
}

// Call without creating object
int result = MathUtils.add(5, 3);

No access to instance variables or methods
Cannot use 'this' keyword
Called using ClassName.method()

Non-Static Methods: Belong to object instance.

class Person {
    String name;
    
    void greet() {
        System.out.println("Hello, " + this.name);
    }
}

// Call on object instance
Person p = new Person();
p.name = "John";
p.greet(); // Hello, John

Can access instance and static members
Can use 'this' keyword
Called on object reference

Comparison:

Feature	Static	Non-Static
Belongs to	Class	Object
Memory	Single copy	Separate copy per object
Access to instance vars	No	Yes
Access to static vars	Yes	Yes
Keyword 'this'	No	Yes
Call syntax	ClassName.method()	object.method()
Use case	Utility methods	Object behavior

Static Block: Executes when class loads, before main method.

static {
    // Initialization code
}

Best Practice: Use static for utility functions; avoid for state that varies by instance."
