[sivasayanth]

hi good morning here

i could not get the idea. that is, what does it( interface ) mean in java?

Have you refer any material about it?

Anyway, interface is quite similar to an abstract class, means members are not implemented. Or group of method which has no body. See the following code.

Code:

interface myInterface
{
int addNumbers(int x, int y);
void isGreat(int val);
// and many more methods which has empty body
}

If you want, deal with access modifiers as well.

If you want to implement it as follows,

Code:

public class MyClass implements myInterface
{
// do the required processing here
}

Think it is clear to you. Anything more.....
