First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).

Then create a new Java application called "RecursiveTriangle" (without the quotation marks)according to the following guidelines.

Modify the example in Horstmann Section 5.9, pp. 228-230 so that the triangle displays in reverse order as in the example below, which allows the user to set the number of lines to print and the String used for printing the triangle.

Use a method to prompt the user for the number of lines (between 1 and 10) to print. This method should take no parameters and return an int value.

Use a method to prompt the user for the string to be used when printing the pattern. This method should take no parameters and return a String value.

Use a method called printTriangle that takes an int and a String as parameters (i.e., the return values from the two methods mentioned above) and has no return value. That method should use recursion to print the reversed triangle as in the following example.

EXAMPLE: The call to printTriangle(numLines, pattern) should print the following, assuming numLines has the value 4 and pattern has the value [].

[][][][] [][][] [][] [] 

Thoughts

You could write and test each method as you go. Alternatively, you could write the whole program with everything in main and then decompose it into methods.
