hi im confused about this question i have where i am supposed to write one line of code for a rectangles x and y coordinates in the form of (x,y)

here is the question:
Write a CoordinateTester program that constructs a Rectangle object
and then prints its coordinates in the format (x, y). You must use
the getX and getY methods. Also print the expected answer.

public class CoordinateTester
{
public static void main(String[] args)
{
Rectangle box = new Rectangle(10, 20, 30, 40) ;

if anyone could please help me out it will be greatly appreciated!

could be anything, look into the Rectangle class and see what methods you have available.
Then print it something like println("X: "+box.getSomething()+"Y: "+box.getSomethingElse());

And the question is?
Use printf for the floating point format. Also you could ask your professor which of those four coordinates from new Rectangle(10, 20, 30, 40) are you supposed to print.
And let me say it AGAIN, without the Rectangle class I have to guess what is what and what is being asked from you.

Ok, then you should have enought information to write the line he asks. Try writing it down and we´ll see how it goes.

System.out.println("X: "+box.getX()+"Y: "+box.getY());

i used your format but still havent recieved the same output.
i got: X: 10.0 Y: 20.0

So maybe you should rewrite it so that it outputs what you need? Like System.out.println("Expected: ......
Try changing the code you posted before and see what the changes do with the printed text. Or try reading some tutorial.

You wouldn´t learn anything if I just simply told you the answer, so try figuring it out on your own.

thats very true i wouldnt learn anything if you told me the answer. i was hoping if you could explain how you derive the answer itself! ive changed the code to make it (x,y) but i still dont get the correct output. i dont know what im doing wrong

So how are you supposed to print the word expected if you cant use it? Does your professor even know what he actually wants from you?
