Need more details. What exactly are you having problems with? For #2, you'll have a main function:

public static void main (String args[])

and your job is to grab two elements from the args[] array, then use concat to turn two Strings into one String. For #3, you can set up a Scanner object to read in the input.

For #1, set up a Frame and a mouse listener, grab your two points in the mousePressed function, and from those two points, figure out the top left coordinate and the width and height of the Rectangle , then paint the Rectangle .

That should give you a start. Give it a try, take it as far as you can, then post some code and a specific question. These are three separate programs, presumably, so consider starting three separate threads.
