Question

So, I have an abstract class acting as a parent class, here’s what I want to happen.

In abstract class:

public void run(){
    while(!booleanStatement){
        //do specific stuff here
    }
}

In child class:

public class extends parentClass{
public void run(){
    //do child stuff here effected by the while loop above
}

Is there any way to make this happen? super() maybe?

Answer 1

Sure. Just define an additional abstract method:

public final void run(){
  while(!booleanStatement){
    doRun();
  }
}

public abstract void doRun();

In this scenario the subclass can’t overwrite run() and is forced to provide an implementation for doRun() which does the work inside the loop.
