Round 1 - Technical 

(4 Questions)

  • Q1. Java oops features
  • Q2. Explain oops features
  • Ans. 

    OOPs features include encapsulation, inheritance, polymorphism, and abstraction.

    • Encapsulation: Bundling data and methods that operate on the data into a single unit (class).

    • Inheritance: Ability to create new classes based on existing classes, inheriting their attributes and methods.

    • Polymorphism: Ability to use a single interface to represent different data types or objects.

    • Abstraction: Hiding the implementation details...

  • Answered by AI
  • Q3. Why string is immutable
  • Ans. 

    String is immutable in order to ensure data integrity and security.

    • Immutable strings prevent accidental modification of data.

    • Immutable strings allow for safe sharing of data between different parts of a program.

    • Immutable strings help in thread safety by avoiding concurrent modification issues.

    • Example: String str = "hello"; str.concat(" world"); // This does not modify the original string, but creates a new one

  • Answered by AI
  • Q4. What is difference between string and string builder
  • Ans. 

    String is immutable while StringBuilder is mutable in Java.

    • String is immutable, meaning once created, it cannot be changed. StringBuilder is mutable, allowing for modifications.

    • String concatenation creates a new string object each time, while StringBuilder allows for efficient string manipulation.

    • StringBuilder is more efficient for concatenating multiple strings in a loop.

    • Example: String str = "Hello"; StringBuilder sb...
