Java 8 reference to a static method vs. instance method

Question

say I have the following code

public class A {
    int x;
    public boolean is() {return x%2==0;}
    public static boolean is (A a) {return !a.is();}
}
         


        

Answer 1

We can not use not static methods or non-global methods by using className::methodName notation. If you want to use methods of a particular class you have to have an instance of the class.

So if you want to access is() method then you can use : 
A a = new A();
a.is();
OR 
(new A()).is();

Thanks.
