Overriding default interface methods

Question

I have found in Java Tutorials here this sample code:

public interface Flyer {
    default public String identifyMyself() { //<- the default modifier gives an error
        return "I am able to fly.";
    }
}

I tried to compile it but as I stated it eclipse gives me an error: Syntax error on token "default", delete this token .

My question is why I cannot run the above code? In fact I cannot run the whole example. Was the default modifier for interface methods introduced after some Java version (I am using 1.6 I think)?

Answer 1

Java 1.8中引入了 默认接口方法 。

Answer 2

Answer 3

Java 8中引入了默认方法，因此它们在Java 6中将不起作用。
