Check if a object is a instance of a class (but not a instance of its subclass)

Question

For this example:

public class Foo{}

public class Bar extends Foo{}

....

void myMethod(Foo qux){
   if (checkInstance(qux,Foo.class)){
     ....
   }
}
         


        

Answer 1

    package com.instance;

    public class Foo {
        public void instance(Foo f) {
            System.out.println("---------");
            System.out.println(f.getClass());
            System.out.println(getClass());
            if (f.getClass() == getClass()) {
                System.out.println("Yes");
            } else {
                System.out.println("No");
            }
        }
    }


package com.instance;

public class Main {

    /**
     * @param args
     */
    public static void main(String[] args) {
        Foo f1 = new Foo();
        Foo f2 = new Foo();
        Foo f3 = new Bar();
        f1.instance(f1);
        f1.instance(f2);
        f1.instance(f3);
    }
