Question

Working in java programming. I have a class (call it manage) that takes in an arraylist (list) and a boolean (switch), which is created/preset in the parent main function above this class. The arraylist is modified and returned to the main function however, hence it's name 'manage.' I need help declaring the arraylist in the constructor?

public class manage{
public manage(){ //Constructor
// What is arraylist construction?
this.switch = false;

}

public manage(ArrayList<Integer> list, boolean switch) {
this.list = list;
this.switch = switch;

...method that I'm working on

}

}
