public class EqualsTest{
public static void main(String[]args){
Moof one=new Moof(8);
Moof two=new Moof(8);
if(one.equals(two)
{
System.out.println("one and two are equal");
}
}
}
class Moof{
private int moofValue;
Moof(int val){
moofvalue=val;
}
public int getMoofValue(){
return moofValue;
}
public boolean equals(Object o)
{
if((o instanceof Moof) && (((Moof)o.getMoofValue()==this.moofValue)){
return true;
}
else{
return false;
}
}
}    

in the overriden equals method how can o instanceof Moof be true?
is it because two is instanceof Moof?

Right, here temporary object 'o' , holds the reference of object Moof 'two' , thats mean 'two' is instance of "Moof' . Dont get confused with Generic Object instance to that of Moof object , here 'o' is just a reference , which can hold any Valid Java object !
