Why it return false?hashCode also equal

Question

I am trying to solve this but it returns false. HashCode and data in both literal is the same if

String s1="java";
String s2="JAVA".toLowerCase();
System.out.println(s1==s1);

s1.equals(s2) will return true as it compares the value or content of the string. and for `==` will compare the memory location value not the content. — Arvind Maurya, Jan 24 '20 at 05:14

public class HelloWorld{

     public static void main(String []args){
        System.out.println("Hello World");
         String s1="java";
        String s2="JAVA".toLowerCase();
        System.out.println(s1.hashCode());
        System.out.println(s1.hashCode());
        System.out.println(s1==s2);
        System.out.println(s1.equals(s2));
     }
}

.equals() will compare the value of variables.

== will compare the value of variable memory locations.

Hashcode is calculated based on the content of the string and not the location of string.

As you are using String class, it is of reference type find documentation here
