Specific code: (Recommended learning: java course)

interface A{
    void a1();
}
 
interface B{
    void b1();
}
 
interface C extends A,B{//注意该语法只对接口的继承是合法的
    void c1();
}
 
class D implements C{
 
    @Override
    public void a1() {}
 
    @Override
    public void b1() {}
 
    @Override
    public void c1() {}
}
