Thread: Simple Problem!

Hello,

I was trying to write a program that checks if any of the numbers that the user inputs are divisible by 3 5 or both. If the number is divisible by 3 it prints out "Fizz", if divisible by 5 then "Buzz" and lastly "FizzBuzz" for both. The program should also print out the other numbers anyway, which are not divisible by either 3 or 5.

E.g. input : 15

Output:
1
2
Fizz
4
Buzz
Fizz
7
8
Fizz
Buzz
11
Fizz
13
14
FizzBuzz

My code is below and I have attached a picture of the current output. Why is it like this? How do I make it work the way I want?

P.S. The first bit of code which I have enclosed between /* */ is another solution of the problem by another person. I do not understand it, however, hence I tried doing it on my own! If somebody would also like to explain how it works to me I would be more than grateful!

 
public class ArrayExample {
	public static void main(String args[])
	{
		/*String words[] = new String[Integer.parseInt(args[0])];
		for(int i = 0;i < words.length;++i)
		{
			words[i] = ""+(i+1);
		}
		for(int i = 2;i < words.length;i += 3)
		{
			words[i] = "Fizz";
		}
		for(int i = 4;i < words.length;i += 5)
		{
			words[i] = "Buzz";
		}
		for(int i = 14;i < words.length;i += 15)
		{
			words[i] = "FizzBuzz";
		}
		for(int i = 0;i < words.length;++i)
		{
			System.out.println(words[i]);
		}*/
 
 
 
	for (int i=0; i<args.length; i++) //MY OWN SOLUTION BEGINS 
	{
 
		for (int j=0; j<Integer.parseInt(args[i]); j++)
 
		{
			if (Integer.parseInt(args[i])%3==0) 
 
			{
				System.out.println("Fizz");
			} 
 
			if (Integer.parseInt(args[i])%5==0) 
 
 
			{
				System.out.println("Buzz");
 
			} 
 
			if (Integer.parseInt(args[i])%15==0) 
 
 
			{
				System.out.println("FizzBuzz");
 
			} 
 
 
		}
		System.out.println(args[i]);
	}	
 
	}
}

Currently the program prints out this:

thank you. Have found a solution, not sure why I never thought of this before!

for (int i=1; i<=Integer.parseInt(args[0]); i++) 
	{
 
 
            if (i%15==0) 
 
 
    		{
				System.out.println("FizzBuzz");
 
			}			 
			else if (i%5==0) 
 
 
			{
			System.out.println("Buzz");
 
 
			} 
            else if (i%3==0) 
 
    		{
				System.out.println("Fizz");
 
			} 
 
        else{
           System.out.println(i);
 
        }

Any chance somebody can explain the below code to me?

String words[] = new String[Integer.parseInt(args[0])];
		for(int i = 0;i < words.length;++i)
		{
			words[i] = ""+(i+1);
		}
		for(int i = 2;i < words.length;i += 3)
		{
			words[i] = "Fizz";
		}
		for(int i = 4;i < words.length;i += 5)
		{
			words[i] = "Buzz";
		}
		for(int i = 14;i < words.length;i += 15)
		{
			words[i] = "FizzBuzz";
		}
		for(int i = 0;i < words.length;++i)
		{
			System.out.println(words[i]);
		}

What do you think it does? Try commenting it, and repost your version with the comments.

No worries, I managed to figure it out !
