Here is an example that accepts two arguments from the user. If the number of arguments is not equal to two then invalid parameter exception is thrown ,otherwise display the two arguments.

import java.util.*;

class InvalidParameterExceptionExample 
{
    public static void main(String[] args)throws Exception
    {

    for (String s: args) {
        if(args.length==2){
        System.out.println(s);
        }
        else{
             throw new Exception("Invalid Parameter Exception");
          }
        }
    }
}
