Thread: My Code has no output

i need help with my code its intended to read from a file and take data and assign the first two numbers it reads as the size of the matrix, then i need it to display a matrix that assigns a number to a certain location in the matrix. IT MUST BE IN METHODS

i want it to read from a .dat file in the format of the following:

10 10
2 3 5
2 8 1
1 9 2
0 1 8

I want the out put to be:

0 0 0 0 0 0 0 0 0 0
0 8 0 0 0 0 0 0 0 2
0 0 0 5 0 0 0 0 1 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0

 
import java.util.Scanner;
import java.io.*;
 
class lab16a
{
	int[][] rix;
	public void size(int rows, int cols)
	{
		rix = new int[rows][cols];
		return;
	}
	int rowsets,colsets,saves;
	public void store(int rowsets, int colsets, int saves)
	{
		rix[rowsets][colsets]=saves;
		return;
	}
	public void show()
	{
		for(int rowcount=0;rowcount<rix.length; rowcount++)
			{
				for(int part=0;part<rix[rowcount].length;part++)
				{
					System.out.print(rix[rowcount][part]+" ");	
				}
				System.out.println();
			}
	}
	public static void main (String[] args) throws FileNotFoundException
	{
		lab16a Run = new lab16a();
		Scanner loc = new Scanner (System.in);
		System.out.println("Input File Location");
		String File = loc.next();	
		loc = new Scanner (new File (File));
		int row=loc.nextInt();
		int	col=loc.nextInt();
		Run.size(row,col);
		while(loc.hasNext())
		{
			int rowset=loc.nextInt();
			int colset=loc.nextInt();
			int save=loc.nextInt();
			Run.store(rowset,colset,save);
 
		}
                Run.show();
	}
 
}

when i run the program i insert the file location and then it just completes the process and it doesnt show the matrix at all. why does the code not have an out put cause i ask it to output in the show method ?

I don't understand what you mean in your question, sorry but i am new at this and my teacher said that if i write the method it will work so what should i do different

--- Update ---

oh okay thank you i figured it out after a min of thinking about what you said i commanded a "Run.show();" 2 } at the bottom of my main method
