Can we instantiate an abstract class directly? [duplicate]
You can't directly instantiate an abstract class, but you can create an anonymous class when there is no concrete class:
public class AbstractTest { public static void main(final String... args) { final Printer p = new Printer() { void printSomethingOther() { System.out.println("other"); } @Override public void print() { super.print(); System.out.println("world"); printSomethingOther(); // works fine } }; p.print(); //p.printSomethingOther(); // does not work }}abstract class Printer { public void print() { System.out.println("hello"); }}This works with interfaces, too.
