public class Test {
public static void main(String args[]) {
String s1 = "abc";
//Here is invoking of overriding String hashCode method.
System.out.println("hashCode value "+s1.hashCode()); }
}
Instead of it, I want to get non-overriding Object hashCode method. How do I get it?
The purpose of the hashCode() method is to provide a numeric representation of an object's contents so as to provide an alternate mechanism to loosely identify it. By default the hashCode() returns an integer that represents the internal memory address of the object.
hashCode() Method The hashCode() is a method of Java Integer Class which determines the hash code for a given Integer. It overrides hashCode in class Object. By default, this method returns a random integer that is unique for each instance.
Understanding How hashCode() Works Simply put, hashCode() returns an integer value, generated by a hashing algorithm. Objects that are equal (according to their equals()) must return the same hash code.
Java Object hashCode() is a native method and returns the integer hash code value of the object.
call System.identityHashCode(s1)
instead.
