Hi friend,


public class OverrideExample extends AbstractExam {
public static void abstractMethod(){
System.out.println("The class method in OverrideExample.");
}
public void testInstanceMethod() {
System.out.println("The instance method in abstract.");
}

public static void main(String[] args) {
OverrideExample over = new OverrideExample();
AbstractExam abs = over;
AbstractExam.abstractMethod();
abs.testInstanceMethod();
}
}

------------------------------------------------

public class AbstractExam {
public static void abstractMethod() {
System.out.println("The class method in abstract.");
}
public void testInstanceMethod() {
System.out.println("The instance method in abstract.");
}
}
