A returned value inside another call

Unit 1: Meet Greenfoot · Lesson 1.5 Parameters and Return Values · code exercise, graded

What to write

1. Move the crab three cells DOWN, using setLocation.
2. Do not use move(). Ask the crab where it is, then send it somewhere relative to that.

Your code

Press Run to watch your code on the grid. Nothing is recorded by Run, so press it as often as you like. Step goes one frame at a time, which is the view that actually explains what act() does.

What it is checked against

These are the examples you can see. There are also 2 hidden cases with different setups, so printing the answers below as text passes nothing.

World w = new World(10, 20, 32);
Harness h = new Harness();
w.addObject(h, 4, 2);
h.act();
System.out.println(h.getX() + "," + h.getY());

w.addObject(h, 4, 2);
