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); 
    } 
}
