equals()

[sandhi mridul]

hi,

  
class test{
public int a,b;
public boolean equals(Object other){
try{
Test t=(Test) other;
return(a==t.a && b==t.b)||(a==t.b && b==t.a);}
catch(classCastException c){
return false;}
}
public int hashcode(){
//
//line 1
}}
  

put the correct implementation of hashcode() at line 1.
ans-
return o;
return a+b;
return a^b;

I am not at all getting what is going on in the above code.
need help.

Thanks

The "hashcode contract" defines a relationship between hashCode and equals. This contract is described in the API under the hashCode method of Object.

So the question here is: Given the equals method in this code, what implemention(s) of hashCode would fulfill the contract?

Does that help?
