String Interning()
str.intern() is a method of storing only one copy of each distinct String Value, which must be immutable.
Ensure that all strings having the same contents share the same memory.

Note that, if another String with the same contents exists in the String constant pool, then a new object won't be created and the new reference will point to the other String

What is String interning?

Comment

String interning refers to the concept of using only one copy of a

distinct String value that is Immutable.

It provides the advantage of making String processing efficient in

Time as well as Space complexity. But it introduces extra time in

creation of String

class GFG { 
    public static void main(String[] args) 
    { 
        // S1 refers to Object in the Heap Area 
        String s1 = new String("GFG"); // Line-1 
  
        // S2 now refers to Object in SCP Area 
        String s2 = s1.concat("GFG"); // Line-2 
  
        // S3 refers to Object in SCP Area
        String s3 = s2.intern(); // Line-3 
  
        System.out.println(s2 == s3); 
  
        // S4 refers to Object in the SCP Area 
        String s4 = "GFGGFG"; // Line-4 
  
        System.out.println(s3 == s4); 
    } 
}
