Hello,

can any one please expain me.I have doubt in Object class. Why it is necessary to override hashCode method with equals method. Since without overriding the hasCode method I am getting the proper output but it is always advisable to override hashCode along with Equals.

package com.lara;

public class B { int i,j;

B() {

} B(int i,int j) { this.i=i; this.j=j; } public String toString() { return "i="+i +","+ "j=" +j; } public boolean equals(Object obj) { B b=(B)obj; boolean falg=(i==b.i&& j==b.j); return falg; }

} class Ma { public static void main(String[] args) { B b= new B(10,10); B b1= new B(10,10);

     System.out.println(b.equals(b1));
     System.out.println(b.toString());
     System.out.println(b1.toString());




}

}
