hey you all my friends ,we can not extends interface ,we can only implements it,is it true we can implement more than one
interface ,but can not extends it (not single not more)

run the following code so you could understand difference between extends and implements keyword

//code using extends keyword
import java.io.*;
interface A{}
interface X{}
interface Y{}
class ExDemo extends A,X,Y
{
public static void main(String arg[])
{
int a;
System.out.println("hey it works");
}
}

//code using implements keyword
import java.io.*;
interface A{}
interface X{}
interface Y{}
class ExDemo implements A,X,Y
{
public static void main(String arg[])
{
int a;
System.out.println("hey it works");

}
}
