Parameters with two integers.

[Hello]

Hello there, im stuck at something here. I'm new to Java, and i have this issue. I'll try to explain as good as i can.

I have written a method called printNumbers, in this method it has a paramater including two integers ( public static int printNumbers (int x, int y) ), i want it to print all the numbers from 1 up to (and including) the value of the first parameter. The second parameter detemines how many numbers to be printed on each line. And in the main method i use scanner as user input. Could anyone help me out here?
Here is an "psudo" picture i made to illustrate the problem.

If I understand your problem correctly...

int total = 0;

for(int i=1;i<x+1;i++)
{
total+=x;
}

You are probably already using a loop to print so just add this in there. Remember that you are starting at 1, not 0.

Hello joey, thanks for reply. I finaly got it to work. Here you can see how i solved this.

import java.util.Scanner;

public class Boka {

	public static void main (String args[]){
		
		Scanner input = new Scanner(System.in);
		
		int number, line;
		
		System.out.print("Max number: ");
		number = input.nextInt();
		
		System.out.print("Numbers each line: ");
		line = input.nextInt();
		
		System.out.print( printNumbers(number, line) );
		
		
	}

	public static int printNumbers(int x, int y){
		
		
		
		for (int i = 1; i < x; i++){
			
			
			if (i % y == 0){
				System.out.printf("%3s \n", i );
			
			}
			else {
				System.out.printf("%3s", i );
			}
		}
		System.out.print(" ");
		return x;
		 
		
		
	
		
	}
	
}

Is there a better way / less code etc.?

Kind Regards Danny

There is ALWAYS a leaner way. Check out ternary operators if you want to have some fun. For readability, though, yours is fine.

Change line #26 to:

    for (int i = 1; i <= x; i++){

Your version forgot that last number (and you don't have to print it in your main( ... ) method as an afterthought)

kind regards,

Jos

Interestingly, I think he got it by accident. He is returning x for some reason, which is being printed out in main.
