Answer Posted / haneef

see, every object created by the new operator, it has it own
hash code.

so when you compare with equals(), checks only content. But
with ==, it also checks the hashcode.

try this example

package app;

public class Test {
public static void main(String[] args) {

String str2 = new String("Haneef");
String str3 = new String("Haneef");

if (str2.equals(str3))
System.out.println("ok");
else
System.out.println("Not OK");

if(str2==str3)
System.out.println("ok");
else
System.out.println("Not ok");
}
}

u get

OK
NOT OK
