Modify Exercise 4.15 to combine your code from the four separate triangles of asterisks such that all four patterns print side by side. Make clever use of nested for loops.

Exercise 4.15

Write an application that displays the following patterns separately, one below the other. Use for loops to generate the patterns. All asterisks (*) should be printed by a single statement of the form System.out.print('*'); which causes the asterisks to print side by side. A statement of the form System.out.println(); can be used to move to the next line. A statement of the form System.out.print(' '); can be used to display a space for the last two patterns. There should be no other output statements in the program.
