JAVA_多态的方法调用

其实在继承链中对象方法的调用存在一个优先级：this.show(O)、super.show(O)、this.show((super)O)、super.show((super)O)。

public class A {
    protected String get(A a){return "A - A";}
//    protected String get(C c){return "A - C";}
}
class B extends A{
    @Override
    protected String get(A a){return "B - A";}

}
class C extends B{

}

class Main{
    public static void main(String[] args) {
        A b = new B();
        C c = new C();
        System.out.println(b.get(c));
    }
}
