suppose in a class there is a code like this:
{
Set hs=new Hashset();
hs.add(new Emp("kathy",1000));
hs.add(new Emp("kathy",2000));
}
how can u avoid the above code in your class as set won't
allow duplicate objects?

Hi,
Can any one provide a full Example for using HashCode and
equals method
class Emp{
private String name;
private int salary;
Emp(String s,int p){
this.name=s;
this.salary=p;
}
public String toString(){
return name+":"+salary;
}
}
// In public static void main method
Set hs=new HashSet();
hs.add(new Emp("kathy",1000));
hs.add(new Emp("kathy",2000));
hs.add(new Emp("kathy",2000));
java.util.Iterator er=hs.iterator();
while(er.hasNext()){
System.out.println(er.next());}
