What is String Pooling in Java?

Can you explain what string pooling is in Java?

String pooling in Java is a memory optimization technique where identical string literals are stored in a common pool.

How does it improve memory efficiency?

It saves memory by reusing existing string objects instead of creating new ones for identical string literals.

Are there any performance benefits?

Yes, it can improve performance by reducing the overhead of creating multiple string objects and speeding up string comparisons.

Can you give an example of string pooling in action?

Sure! When you create a string like String s1 = "Hello"; and then String s2 = "Hello";, both s1 and s2 point to the same object in the string pool.
