Java String.equals() versus ==.

Java 8Object Oriented ProgrammingProgramming

The equals() method compares this string to the specified object. The result is true if and only if the argument is not null and is a String object that represents the same sequence of characters as this object.

Example

Live Demo

public class Sample {
   public static void main(String []args) {
      String s1 = "tutorialspoint";
      String s2 = "tutorialspoint";
      String s3 = new String ("Tutorials Point");
      System.out.println(s1.equals(s2));
      System.out.println(s2.equals(s3));
   }
}

Output

true
false

You can also compare two strings using == operator. But, it compares references to the given variables, not values.

Example

Live Demo

public class Sample {
   public static void main(String []args) {
      String s1 = "tutorialspoint";
      String s2 = "tutorialspoint";
      String s3 = new String ("Tutorials Point");
      System.out.println(s1 == s2);
      System.out.println(s2 == s3);
   }
}

Output

true
false
