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.

Everytime i do the code i get full boxes. I can't seem to figure out how to make them hollow. Question is how is the program supposed to look.

Input:	1	2	3	4	5	6
Output:	*	** **	*** * * ***	**** * * * * ****	***** * * * * * * *****	****** * * * * * * * * ******
