Then create a new Java application called "PatternMaker" $($without the

quotation marks$)$ according to the following guidelines.

The program prompts the user for five input values:

An integer value between $5$ and $15($inclusive$)$ for the number of rows to

be printed

A second integer value between $5$ and $20($inclusive$)$ for the number

of columns to be printed

Note: Value of columns cannot be less than the number of rows.

A string value for the starting string of the pattern

A string value for the second string of the pattern

A string value that separates the first two strings

The program must use nested for loops to print a triangular array of alternating

first and second strings of the pattern, separated by the separator string, and

such that the first string in the first row uses the "first string" provided by the

user, but each subsequent row alternates the starting string between the

"second string" the user provided and the "first string" the user provided.

So$,$ for instance, if the user enters $5$ for the number of rows, $7$ for the

number of columns, and $"$MM$"$ for the first string, $"$OO$"$ for the second

string, and $"***"$ for the separator $($not counted as a column$),$ your program

should print the following TRIANGLE pattern.

$M{M}^{****}{?}^{**}00****M{M}^{****}{?}^{**}00***MM$

$00******M{M}^{****}{?}^{**}00******MM$

$M{M}^{******}00******MM$

Thoughts and Hints

Note the requirement for this program to use nested for loops

$($Horstmann section $4\mathrm{.}3).$

Note that there is no separator at the end of the lines.

Make sure rows does not exceed columns $---$ in your testing.

The logic needed for the nested for loops is a bit tricky. Try writing out

the logic for simple cases $($e$.$g$.,2$ rows and $3$ columns$).$

Try to get the output to print as a rectangle first, then try to modify to

make the triangle

Example below shows the above output as a rectangle instead of a

triangle:

$\{\begin{array}{ccc}\text{:}M{M}^{****}{?}^{**}00& ***& M{M}^{****}{?}^{**}{00}^{****}{?}^{**}M{M}^{****}{?}^{**}{00}^{****}{?}^{**}MM\end{array}$

Include multiple runs of this program using a variety of values for the three

input strings and input integers.

Copy and paste all of your sample runs in your source code as a block

comment at the bottom below the closing curly brace.
