Homework Help: Java

Posted by Robert on Tuesday, December 15, 2009 at 11:04am.

Write a GUI application that prompts the user for a number between 1 and 5. Be sure to include error checking so that the program continues to prompt the user for a number until the user's entry is between 1 and 5, inclusive.

Once a valid number is entered, the program should display a grid of horizontal and vertical lines inside the frame.
These lines should be drawn such that:

• The lines create x number of horizontal and x number of vertical boxes, where x is the number entered by the user.

• Each box should be 100 pixels by 100 pixels.

• The grid is spaced inside the frame such that it is perfectly centered both horizontally and vertically, with a 10-pixel border between the edge of the frame and the grid.

I cannot figure out how to make a border with the gridlayout. Please help!
