Q2. What is JIT in java
Ans. 
JIT stands for Just-In-Time compilation in Java. It dynamically compiles bytecode into machine code at runtime for improved performance.
• JIT is a part of the Java Virtual Machine (JVM) that optimizes the execution of Java programs.

• It analyzes the frequently executed parts of the bytecode and compiles them into native machine code.

• This compilation happens at runtime, just before the code is executed, hence the name Just-...read more

Q1. How internally work HashMap ?
Ans.

• HashMap stores data in key-value pairs, where each key is unique.

• It uses a hash function to compute an index (hash code) for each key.

• The computed index points to a bucket in an array where the value is stored.

• If multiple keys hash to the same index (collision), they are stored in a linked list or tree structure.

• Example: For a k...read more

Q3. Difference between hash map and hash set?
Ans. 
HashMap stores key-value pairs; HashSet stores unique keys without values.
• HashMap allows duplicate values but not duplicate keys. Example: {1: 'A', 2: 'B', 1: 'C'} results in {1: 'C', 2: 'B'}.

• HashSet only stores unique elements. Example: {1, 2, 2} results in {1, 2}.

• HashMap provides O(1) average time complexity for get and put operations.

• HashSet provides O(1) average time complexity for add, remove, and contains operati...read more
