That's not a question, it's an assignment. Is it homework that you should be doing? People here are not going to do it for you, although they will help you if you get stuck somewhere along the way.

In the meantime, you could also read up on How to ask questions on JavaRanch, particularly the section on "Do your own homework".

see if I can point you in some direction.

think of a square.
each corner of the square has a point location (x,y).

can you draw diagonal lines between these points:
x,y top left to x,y lower right
x,y lower left to x,y top right

can you draw a horizontal line and a vertical line, between the corner x,y positions.

if you can do this, all you have to do is put them in the right order,
add a runnable thread (or timer), and you have your assignment done.

note: the horizontal/vertical lines will be slightly shorter than the diagonals,
so you may have to include an additional calculation if the assignment stipulates
the lines are to be the exact same length.
