How can you get a string from the string pool in Java?

In Java, a string from the string pool is either a string literal or a string explicitly placed in the string pool to save memory.

To get a string from the string pool, you can use the intern() method of the String class.

Example:

String s1 = new String("hello");
String s2 = s1.intern();

// s2 now refers to a string from the string pool

Methods to obtain a string from the pool:

• Using string literals, for example, String s = "text"; — such strings are automatically placed in the pool.
• Calling intern() on a string — if such a string already exists in the pool, a reference to it is returned; otherwise, the string is added to the pool and the reference is returned.

This is useful for saving memory and speeding up string comparison using ==.
