Interface Inheritance : create class that implements the interface

**Zulkifli_Rahman** · 07-08-2012, 08:38 AM

I'm just preparing for my exam. Help me solve this problem.

Java Code:

interface J {
    int j = 200;
    int j1();
}
interface K {
    double k1();
}
interface L extends J,K{
    boolean l1();
}
class I implements L{
    public boolean l1() {
        return true;
    }
    public int j1() {
        return 4;
    }
    public double k1() {
        return 6.8;
    }
}
class InterfaceInheritance{
    public static void main(String[] g){
        I i=new I();
        System.out.println(i.j);
        System.out.println(i.j1());
        System.out.println(i.k1());
        System.out.println(i.l1());
    }
}

Result :
200
4
6.8
true

I just want to learn how to create o class that implements the interface j and k. Then, call the method on a main program in class InterfaceInheritance.

thanks guys for helping me prepare for the exam
