suppose we have an interface & that interface contains five
methods. if a class implements that interface then we have
to bound that to give tha definition of all five methods in
that class. If we declare that class as abstract then can
we call only two methods to give the deinition of that
method & i don't want to give the definition of all the
methods? can it possible
Answer Posted / sitaram
yes it is possible, just make rest of the method abstract
explicitly.
public interface InterfaceSample {
public void method1();
public void method2();
public void method3();
public void method4();
}
abstract class Abstclass implements InterfaceSample{
public abstract void method1();
public abstract void method2();
public void method3(){
System.out.println(" astract method3 ..............");
}
}
public class Sample extends Abstclass {
public void method1(){
System.out.println("method1 ..............");
}
public void method2(){
System.out.println("method2 ..............");
}
public void method4(){
System.out.println("method4 ..............");
}
public static void main(String[] args) {
Sample s1 = new Sample();
s1.method1();
s1.method2();
s1.method3();
s1.method4();
}
}
