I'm not able to instantiate the GuitarAbstract
class
Error:
Cannot instantiate the type GuitarAbstract.GuitarAbstract is an abstract class.
You can't directly instantiate an abstract class, but you can instantiate an anonymous class for your abstract class.
For example, given the following abstract class:
class GuitarAbstract {
public abstract void play();
}
You can create an anonymous class like so:
GuitarAbstract guitar = new GuitarAbstract() {
@Override
public void play() {
System.out.println("Playing guitar!");
}
};
