Question

Java Programming:

Please help me add and improve functionality of this java class which generates X random Integer values between 0 and Y. Program is posted below

/* Name: RandomIntGenerator.java
* Purpose: Create a number generator
* using command line input for how many to generate
* and the range in which to generate.
*/
public class RandomIntGenerator{
    
    public static void main(String[] args){
        
        if (args.length == 2){
            
            //Parse the command line input arguments to integers
            int xGeneratorCount = Integer.parseInt(args[0]);
            int yGeneratorRange = Integer.parseInt(args[1]);
            
            
            //Loop through xGeneratorCount
            for (int i = 0; i < xGeneratorCount; i++){
                //Generate random numbers from 0 to yGeneratorRange inclusive
                int myGeneratedNumbers = (int) (Math.random() * (yGeneratorRange + 1) );
                
                //Print out random numbers that are generated
                System.out.println("Random Number "+(i+1)+": "+myGeneratedNumbers);
            }
                        
        }else{
            //Output error message if arguement length is not equal to 2
            System.out.println("Invalid input. Use following format: "+
            " java RandomIntGenerator <int x> <int y>"+
            " Where x is the integer specifying Generator Count and y is the integer specifying Generator range.");
        }
        
    }

}
