I'm still having difficulty because I cannot believe my ability. Please make programming easy and short.

Develop a complete java program that produces a square pattern of asterisks and spaces. First prompt the user for the size of the pattern, then use for loops to print out the pattern. If the user enters a value that is not a number your program's behavior is arbitrary. For non-positive values your program should print nothing and end normally. Your program should work for input values up to the width of the terminal window. Examples for the first 6 values are shown below. Input: 1 2 3 45 6 Output: **X* You should use nested for loops to solve this
