Thread: [HELP] [HELP] Trouble To Understanding The Algorithm of my project

So, Let's get to the point. I need some hint for the algorithm for my project.
The program should has the output depending the number I'll input. (The number should be from 1-9)
This is the program's output should be:

Input number: 4
 
Output:
# # # 1 # # # # # 
# # # 2 # # # # # 
# # # 3 # # # # # 
1 2 3 4 5 6 7 8 9 
# # # 5 # # # # # 
# # # 6 # # # # # 
# # # 7 # # # # # 
# # # 8 # # # # # 
# # # 9 # # # # #
 
 
(Example 2):
Input numbers: 8
Output:
# # # # # # # 1 # 
# # # # # # # 2 # 
# # # # # # # 3 # 
# # # # # # # 4 # 
# # # # # # # 5 # 
# # # # # # # 6 # 
# # # # # # # 7 # 
1 2 3 4 5 6 7 8 9 
# # # # # # # 9 #
 
(Example 3):
Input number: 5
Output:
# # # # 1 # # # # 
# # # # 2 # # # # 
# # # # 3 # # # # 
# # # # 4 # # # # 
1 2 3 4 5 6 7 8 9 
# # # # 6 # # # # 
# # # # 7 # # # # 
# # # # 8 # # # # 
# # # # 9 # # # #

Anyone can help me? I'm not asking the code to make this program, I have trouble to understand the algorithm to make this program
Sorry, my English isn't good enough.

A pattern of rows and columns printed with 2 loops (one nested in the other) with special characters output on the designated row and column.

I suggest you start by writing nested loops that print a 9x9 block of '#' symbols and then work on the input/special row and column part. The outer loop controls the rows, the inner loop prints the character along each row making the columns.

Surely you've done something similar.

Yes I've done something similar, Do you mean like this?

package projek1;
/**
 *
 * @author Hengky
 */
public class Projek1 {
    public static void main(String[] args) {
        for (int i = 1; i <= 9; i++) {
 
            for (int j = 1; j <= 9; j++) {
                System.out.print('#');    
            }
            System.out.println("");
 
        }
    }
 
}
 
The output:
#########
#########
#########
#########
#########
#########
#########
#########
#########

I just change the print '#' into j if I want the ouput print numbers, right?
Then from here what next?

Excellent start!

First get the user's input (use a Scanner object), then you'll use an 'if' statement to do pretty much what you've described, something like:

if ( j = userInput )
{
    // do something different
}
 
if ( i = userInput )
{
    // do something different
}

Hey Thanks!! I Solved this because your help.
I have another project, I hope you can guide me to complete the project like what you did in my thread here
