Interview Questionnaire 

3 Questions

  • Q1. 1.What is the purpose of a default constructor?
  • Ans. 

    The purpose of a default constructor is to initialize the object's instance variables with default values.

    • A default constructor is automatically provided by the compiler if no constructor is defined in the class.

    • It is used to create an object of the class with default values for its instance variables.

    • Default constructors are useful when we want to create an object without passing any initial values.

  • Answered by AI
  • Q2. 2.What are the differences between the constructors and methods?
  • Ans. 

    Constructors are special methods used to initialize objects, while methods are regular functions that perform specific tasks.

    • Constructors have the same name as the class, while methods have unique names.

    • Constructors are called automatically when an object is created, while methods need to be called explicitly.

    • Constructors do not have a return type, while methods have a return type.

    • Constructors are used to set initial v...

  • Answered by AI
  • Q3. 3.Why is the main method static?
  • Ans. 

    The main method is static because it needs to be called by the Java Virtual Machine (JVM) without creating an instance of the class.

    • Static methods can be called directly using the class name, without creating an object of the class.

    • The main method is the entry point of a Java program, and it needs to be called by the JVM to start the execution.

    • If the main method were not static, we would need to create an object of the...

  • Q1. What is autoboxing and unboxing
  • Ans. 

    Autoboxing is the automatic conversion of primitive data types to their corresponding object wrapper classes.

    • Autoboxing is useful when working with collections that require objects instead of primitives.

    • Example: int i = 5; Integer j = i; //autoboxing

    • Unboxing is the opposite of autoboxing, where an object of a wrapper class is converted back to its corresponding primitive type.

    • Example: Integer j = 5; int i = j; //unboxi

  • Q1. 

    Nth Fibonacci Number Problem Statement

    Calculate the Nth term in the Fibonacci sequence, where the sequence is defined as follows: F(n) = F(n-1) + F(n-2), with initial conditions F(1) = F(2) = 1.

    Input:

    ...
  • Ans. 

    Calculate the Nth Fibonacci number efficiently using dynamic programming.

    • Use dynamic programming to store previously calculated Fibonacci numbers to avoid redundant calculations.

    • Start with base cases F(1) and F(2) as 1, then iteratively calculate F(n) using F(n-1) and F(n-2).

    • Ensure the input N is within the constraints 1 <= N <= 10000.

    • Example: For N = 5, the 5th Fibonacci number is 5 (1, 1, 2, 3, 5).

  • Ans. 

    Implement a function to return all prime numbers less than or equal to a given positive integer N.

    • Create a function that takes a positive integer N as input

    • Iterate from 2 to N and check if each number is prime

    • Use a helper function to determine if a number is prime

  • Q3. What is a merge join in SQL?
  • Ans. 

    A merge join in SQL is a method of combining two sorted datasets by matching corresponding rows based on a specified condition.

    • Merge join is used when joining two large datasets that are already sorted.

    • It is more efficient than other join methods like nested loop join or hash join for sorted datasets.

    • The join condition must be an equality condition.

    • Example: SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.i
