假设我有2个接口

interface A {

    public static final int CONSTANT1 = 6;

}

interface B {

    public static final int CONSTANT1 = 7;
}

class MYclass implements A, B {

    public static void main(String[] args) {

        System.out.println(CONSTANT1);//<- ??

    }
}

将打印哪个常数，还是编译错误？

最佳答案

只是作为参考，代码如下：

interface A
{
    int CONSTANT1 = 6;
}

interface B
{
    int CONSTANT1 = 7;
}

public class Test implements A, B
{
    public static void main(String[] args)
    {
        System.out.println(CONSTANT1);
    }
}

打印7。
