Answer / tarun
Abstract Class : An abstract class can not be initialized.
Any class can extends it. The methods declared in the
abstract class can be abstract or not.
Abstract Method : If any method is declared as abstract
method it should be in a abstract class. And it can be
override by any other class which is extending it. if method
is declared as abstract it should not contain body.
For Example:
public abstract class AbstractEx {
public void reset(){
System.out.println("The Sun Rises in the east");
}
public abstract void method();
protected abstract void newmethod();
}
