Java 8默认方法潜在问题

public interface InterfaceA {

    void print();


    default void testMethod() {
        System.out.println("Print A");
    }

}

public interface InterfaceB {

    void print();

    default void testMethod() {
        System.out.println("Print B");
    }

}

// 测试类1
public class ClassImpleAB implements InterfaceA{

    @Override
    public void print() {

    }

}


// 测试类2
public class ClassImpleAB implements InterfaceA,InterfaceB{

    @Override
    public void print() {

    }

}
// 报错：ClassImpleAB inherits unrelated defaults for testMethod() from types InterfaceA and InterfaceB
// 必须实现testMethod()方法
