Can the Java interface have a specific implementation

Public interface S {

}

Public interface B {

Public static final S S = new S () {
Public String toString () {
Return "I realized in the interface";
}
public void dostring (String s) {
SYSTEM.OUT.PRINTLN ("I implemented on the interface");
}
};
}

public class Test {

public static void Main (string[] args) {
String s = b.s.tostring ();
System.out.println (s); I implemented it in the interface

}
}

(First of all, although my JDK version is 1.6, 1.8 can write a specific implementation in the interface)

This is a concrete implementation of the interface but my eclipse cannot call to dostring (), so the S interface can only override the 9 major methods of object

Although it is meaningless to make a concrete implementation of the interface by means of anonymous internal classes,

But it does not mean that the interface is not specifically implemented, but that it is not allowed
