Question

is it possible to access child class in parent?

e. g. I want the output of the following code tobe “red blue”.

class Color {
    public final void printName() {
        System.out.println(__Something_Here!!!__.class.getSimpleName());
    }
}

class Red extends Color;

class Blue extends Color;

main() {
    Red red = new red();
    Blue blue = new blue();
    red.printName();
    blue.printName();
}

You can use getClass() to return the class object for any object.

public final void printName() {
    System.out.println(getClass().getSimpleName());
}

See the Javadoc for getClass() for details
