small problem in java

[evan yousif]

Hello I am a student and I am trying to write a code that does this

This project will ask a user to input a number for example "please Enter a vaule of N"

and a user types 30 and then the java code will display on the scren like this

0 1 2 3 4 5 6 7 8 9

10 11 12 13 14 15 16 17 18 19

20 21 22 23 24 25 26 27 28 29

30

same like that and so and so for if he choose a number more than 30 it will show till the number he chose
and it has to print 10 numbers each line
I don't know how to do nothing seems to be working here
is my code

package arrays;

import java.util.Scanner; 
 public class Arrays{ 
 public static void main(String args[]){ 



 Scanner input = new Scanner(System.in); 
 int N; 
 System.out.print("Please Enter A Value Of 'N': "); 

 N = input.nextInt(); 

 int rows ; 
 int columns ; 
 int i, j; 
 for (i=0; i < N; i++){ 

 for (j=0; j < N; j++) 

 { 

 System.out.print( i+j +" ") ; 
 } 
 System.out.println(); 
 } 


 } 

 }

and this is the out put ( hint I chose number 10 for the input )

that's the out put I got when I run my code

1 2 3 4 5 6 7 8 9 10 
2 3 4 5 6 7 8 9 10 11 
3 4 5 6 7 8 9 10 11 12 
4 5 6 7 8 9 10 11 12 13 
5 6 7 8 9 10 11 12 13 14 
6 7 8 9 10 11 12 13 14 15 
7 8 9 10 11 12 13 14 15 16 
8 9 10 11 12 13 14 15 16 17 
9 10 11 12 13 14 15 16 17 18

Evan,
Welcome to CodeRanch!

On the second row, think about how you want to figure out the number. It's not 1+0. It's 10+1+0. How could you reflect that in your code? Any ideas?

[evan yousif]

thanks for replaying, however I am very new in this and no I have no idea!! what you exactly mean

[Jeanne Boyarsky]

Let's try this another way. This line doesn't do what you want:

System.out.print( i+j +" ") ; 

When i=0 and j=0, it prints 0 - good
When i=0 and j=1, it prints 1 - good
When i=0 and j=2, it prints 2 - good
When i=1 and j=0, it prints 1 - not good
When i=1 and j=1, it prints 2 - not good
When i=1 and j=2, it prints 3 - not good

For the three "not good" ones, what do you want printed instead? What is it off by?

[evan yousif]

I don't know what you exactly asking! I need the thing to print till the number of the user input example if the user input 10 I want it to display like this

0 1 2 3 4 5 6 7 8 9
10

and it will stop till 10

Turn your computer off and use a pencil and paper (and eraser, which is an important tool ‍) to write how you intend to do it. What would the instructions be? When you have those instructions really simple, you will be able to change them into code.

This is not how you help each other! you guys should show us how to do it sicne you guys are expert! each one of you told me to do something that is out of my question you guys could of just showed me and I was going to know what I did wrong

to those who have same problem as I did I was able to fix it here is the code

package javaapplication1;

import java.util.Scanner;
/**
 *
 * @author K
 */
public class JavaApplication1 {

    public static void main(String[] args) {
        int n; // you can change the size of array by changing the value of n
        System.out.print(" enter the value of n");
        Scanner in = new Scanner(System.in);
            n = in.nextInt();
        
       
        
         for(int i=0;i<=n;i++){
     
            if(i%10==0)
            {
                System.out.println("\n");
            }
            System.out.print(i + "      ");
        }
        
    
}
}

Evan,
by providing code as a solution is never going to help in the long run.
I am not an Java expert by any means, but I know that you learn the best only by brainstorming.
Coderanch is there to help every one, but not providing complete code as a solution.
I hope experts agree with me.

Jeanne and Campbell were actually showing you how to solve the problem.
If you think they are experts, listen to them and follow their suggestions which is the best way to get to the solution.

[Campbell Ritchie]

I couldn't have put it better than Tapas Chand did

Thank you.

[Tapas Chand]

Actually thank YOU.
From april 2015 I am following code ranch regularly and learning new things literally everyday.
Learning has never been easier.

I'm sure you've heard the adage "Give a man a fish he eats for a day. Teach a man to fish he eats for a lifetime." We STRONGLY believe that it is better to teach you how to think through a problem than just spoon feeding you answers. There are other sites that will do that.

Please remember that people here are all volunteers, and give you what time, and what help, they choose - no more, and no less.
