The difference between == and equals in Java

public class Compare { 
 
   
  public static void main(String[] args) { 
    String s1 = new String("Hello,World!"); //Create two string-type object references;
    String s2 = new String("Hello,World!"); 
     
    String s3 = s1;             //Assign a reference to s1 object to s3
     
    System.out.println("s2==s3 The result of operation is :" + (s2==s3)); //Different addresses
    System.out.println("s1==s3 The result of operation is :" + (s1==s3)); //Address is the same
        System.out.println("s2.equals(s3) The result of operation is :"+(s2.equals(s3)));//Content is the same
  } 
} 

Result of s2 = = s3 is: false 
The result of s1==s3 is :true 
The result of s2.equals(s3) is :true 

Conclusion:

The equals() method is a method in the String class that compares two object references to each other. And == compares the addresses of two object references. Since s1 and s2 are two different object references in different locations in memory, the String s3 =s1 statement assigns a reference to s1 to s3, so s1 and s3 are equal object references.
