Q5. What is the purpose of the String Constant Pool in Java?
Ans. 
The String Constant Pool optimizes memory usage by storing unique string literals in Java.
• Strings are immutable in Java, meaning once created, they cannot be changed.

• The String Constant Pool is a special memory area in the Java heap.

• When a string literal is created, Java checks the pool first to see if it already exists.

• If it exists, the reference to the existing string is returned; if not, a new string is created.
