不使用子类对象调用抽象超类的方法

Question

Suppose there is an abstract Super class with only one method which has default implementation. Now, sub class is extending super class and it overrides the method of super class.

How to call method of super class without using sub class object?

public abstract class SuperClass
{
    public void test()
    {
      System.out.println("SuperClass test method called");
    }
}

public class SubClass extends SuperClass
{
    public void test()
    {
      System.out.println("SubClass test method called");
    }
}

public class CallAbstract
{
     public static void main(String[] args)
     {
        //How to Call abtract SuperClass test method without using sub class object?
     }
}

Answer 1

Using another anonymous class you could do:

public class CallAbstract
{
   public static void main(String[] args)
   {
      (new BaseClass(){ }).test();
   }
}

Answer 2

You need another Subclass that does not overwrite the test() method.

public class OtherSubClass extends BaseClass {

}

And in your main method:

OtherSubClass osc = new OtherSubClass();
osc.test();

or use an anonymous class, like Edwin Dalorzo suggests.
