How can you access a string object from the string pool in Java?

In Java, string literals are stored in the String Pool for memory optimization. To access a string object from the String Pool, you can use the intern() method of the String class.

The intern() method returns a string from the pool if it already exists, or adds the current string to the pool and returns it.

Example:

String s1 = new String("hello");
String s2 = s1.intern(); // s2 refers to the string from the pool
String s3 = "hello"; // string literal from the pool

System.out.println(s2 == s3); // true

Thus, intern() allows you to get a reference to a string from the String Pool.
