java programming language

Write a program that displays pascal's triangle (see Programming Project 7 from Chapter 4 of Reges or http://en.wikipedia.org/wiki/Pascal%27striangle for examples). Your program should take two command line arguments. The first is the number of rows of the triangle to display. The second is an optional argument for the modulus. If no modulus is given generate Pascal's triangle as normal. Otherwise, reduce each entry in the triangle mod the given modulus. Use System.out.printf) to format (or manually format) the output into appropriately sized fields so the triangle is displayed correctly (e.g. such as in the example for Project 7 in Chapter 4 of Reges). Be sure not to have either too little or too much space in between each field. As a hint, you may want to generate the triangle twice. Once to find the maximum value (to set the field size) and once to print the triangle. 2
