There is a very quick and easy way to solve that question: Google. good luck.

I only found the difference between an Interface and an Abstract class. But thanks anyways

Public classes are explained on this page, and abstract classes are explained here.

Apples and oranges. Abstract classes can be public, but they don't have to be. Public classes can be abstract, but they don't have to be. So I guess that's more like comparing apples to fruit?

An abstract class is kind of a template class which cannot be instantiated w/o adding some concrete code to it. A public class is simply a class that may be accessed by any other class w/o further restrictions.

You sure about that definition?

Code java:

---

public class Test{
   public static void main(String... args){
      AbstractTest at = new AbstractTest(){};
      ExtendingClass et = new ExtendingClass();
   }
}
 
public abstract class AbstractTest{}
public class ExtendingClass extends AbstractTest{}

As told earlier both are different concepts.

Hi,

abstract class can contain zero or more abstract methods. It mean if a class contain abstract methods declare that class as abstract class by using abstract keyword. But whenever we apply the public on a class , it is possible to access that class inside and outside the package. That's why both are different.
