Objective: Triangle program $-$ Create a method that takes an integer input n and outputs a triangle of the $*$ character that is n in length. In the main method prompt the user to enter a whole number and pass that number to your method.

Details: You are required to have a static method in this assignment in addition to the static main method. The static method should be a void method that takes a single integer variable, n$,$ as its input. The static method then follows these steps $($Note that I use indention to signify steps within a loop$)$:

Open a file called "triangle.txt$"$

Set up a PrintWriter to output to triangle.txt $($see lecture video for example$)$

Create a for loop that starts at i $=0$ and ends at i $<$ n

Within the for loop create a second for loop that starts at j $=0$ and ends at j $<($i $+1)$

This is called a nested loop. It is when you have a loop inside of another loop

Within the nested loop write $"*"$ to the file using the $.$write$()$ method in PrintWriter

Example: If my PrintWriter object is called fileWriter I would call: fileWriter.write$("*")$;

After the nested loop ends, write $"$

$"$ to the file using the $.$write$()$ method in PrintWriter

After both loops and before your function returns call the $.$close$()$ method in PrintWriter to guarantee everything is output to the file
