Hi Friends,

Can anyone tell exactly,at wat situation we have to go to abstract class and at wat situation we have to go to interfaces.

And also in this code

interface i1
{
public void method1();
}
interface i2{
public void method1();}
class sample implements i1,i2{

// here we have to implement two method1() or just one is enough?
}

// here we have to implement two method1() or just one is enough?

That's a good question. What happened when you tried it?

As far as abstract classes and interfaces go, google:+java +"abstract vs interface" yields 15000 results. An embarassment of riches! Perhaps you could start with Maximize flexibility with interfaces and abstract classes from JavaWorld.

Also I think you may have homework dumped the wrong question!

Seriously though, you will learn a *lot* more by expressing an opinion based on what you have read and tried than by offering pleas to forum based oracles. You won't get flamed if it's clear you're trying.
