    public Interface method() {
        final int i = 0;
        return new Interface() {
            public int publicMethod() {
            return i;}
        };
    }
}
public class Class {
    public Interface method() {
        final int i = 0;
        return new MyInterfaceClass(i);
    }
}
public class MyInterfaceClass implements Interface {
    private final int
               i;
    public MyInterfaceClass(int i) {
        this.i = i;
    }
    public int publicMethod() {
        return
               i;
    }
}
