Question

I am given a class that has a private method say setCoors(int x, int y). The constructor of that class has the setCoors in it too. In a different class, I want to have a method setLocation which calls setCoors. Is this possible?

New Question:

If I am not allowed to set the method to public, is this possible?

public class Coordinate{
    public Coordinate(int a, int b){
        setCoors(a,b)
    }
    private void setCoords(int x, int y)
}

public class Location{
    private Coordinate  loc;
    public void setLocation(int a, int b)
        loc = new Coordinate(a,b)
}

Answer 1

No, private means the method can only be called inside of the Class in which it is defined. You will probably want to have setLocation create a new instance of the class setCoords resides in, or change the visibility on setCoords.

EDIT: The code you have posted will work. Just be aware that any instance of the Location class will be bound to its own Coordinate object. If you create a new Coordinate object somewhere else in your code, you will be unable to modify its internal state. In other words, the line

Coordinate myCoord = new Coordinate(4, 5);

will create the object myCoord which will forever have the coordinates 4 and 5.
