Java String intern() method example.

The intern() method of the String class returns a canonical representation for the string object. It follows that for any two strings s and t, s.intern() == t.intern() is true if and only if s.equals(t) is true.

Example

Live Demo

import java.io.*;
public class Test {
   public static void main(String args[]) {
      String Str1 = new String("Welcome to Tutorialspoint.com");
      String Str2 = new String("WELCOME TO SUTORIALSPOINT.COM");
      System.out.print("Canonical representation:" );
      System.out.println(Str1.intern());
      System.out.print("Canonical representation:" );
      System.out.println(Str2.intern());
   }
}

Output

Canonical representation: Welcome to Tutorialspoint.com
Canonical representation: WELCOME TO SUTORIALSPOINT.COM
