Answer to UnknownHero's Q2 of his Exam2.

I only had to change 1 method from my previous program for Q1, ahh the goodness of software reuse

import java.io.*;

public class exam2 {
	
	private static String input = "";
	private static BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
	
	/**
 * *Constructor
	*/	
	public static void main(String[] args) {
 *
 *int num = -1;
 *
 *try {
 *	
 *	num = getNumber("a number");
 *	in.close();
 *}
 *catch(IOException ex) {
 *	ex.printStackTrace();
 *}
 *
 *calcWeirdMethod(num);
	}
	
	
	private static void calcWeirdMethod(int num) {

 *int x = 0;
 *
 *for(int i=1; i <= num; i++) {
 *	x = x+i;
 *}
 *
 *System.out.println("Answer is : "+x);
	}
	
	
	/**
 * *Function getNumber(String)
 * *
 * *@exception NumberFormatException
 * *@throws IOException
 * *@return int
	*/
	private static int getNumber(String which) throws IOException
	{
 *boolean stop = false;
 *int num = 0;
 *
 *while(!stop) {
 *	
 *	try {
 * *System.out.print("Enter "+which+": ");
 * *input = in.readLine();
 * *num = Integer.parseInt(input);
 * *
 * *if(num < 0) {
 * *	num = num*-1;
 * *}
 *	
 * *stop = true;
 *	}
 *	catch(NumberFormatException nfe) {
 * *System.out.println("Not a valid integer, try again");
 * *stop = false;
 *	}
 *}
 *
 *return num;
	}
