I'm trying to print a two dimensional array with 5 rows and 5 columns but when I print it, I instead get one line with "[[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]]" How do I print it so that I get a 5x5 grid?

import java.util.Arrays;

public class spil {
    public static void main(String[] args) {
        int[][] grid=new int [5][5];

        System.out.println(Arrays.deepToString(grid));
    }

    public static void print(int[][] grid) {
        for (int i = 0; i < grid.length; i++) {
            for (int j = 0; j < grid[i].length; j++) {
                System.out.print(grid[i][j]+ " ");
            }
            System.out.println();
        }
    }
}

You're calling Arrays::deepToString in line 7 instead of your custom print mehthod.

Instead, use print(grid); to call your method.

Print Two Dimensional Array in Java, Can the rows in a two dimensional array have different lengths? In this post, we will see how to print them. 1. Arrays.toString() We know that a two dimensional array in Java is a single-dimensional array having another single-dimensional array as its elements. We can use Arrays.toString() function to print string representation of each single-dimensional array in the given two dimensional array.

Check this;

   import java.util.Arrays;

   public class spil {

    public static void main(String[] args) {

    int[][] grid=new int [5][5];
    print(grid);// you never called your function
   // System.out.println(Arrays.deepToString(grid));-----> This function was making all printing
}

public static void print(int[][] grid) {
    for (int i = 0; i < grid.length; i++) {
        for (int j = 0; j < grid[i].length; j++) {
            System.out.print(grid[i][j]+ " ");
        }
        System.out.println();
    }
}
}

Two-Dimensional Arrays \ Processing.org, Why do we use two for loops with two dimensional arrays? Here, we are reading number of rows and columns and reading, printing the array elements according to the given inputs. Submitted by IncludeHelp, on December 07, 2017 Read number of rows and columns, array elements for two dimensional array and print in matrix format using java program. Example:

You can just call your print method:

public class Spil { 

   public static void main(String[]  args) {
      int[][] grid = new int[5][5]; 

      print(grid);
   } 

   public static void print(int[][] grid) {
      for (int i = 0; i < grid.length; i++) {
         for (int j = 0; j < grid[i].length; j++) {
            System.out.print(grid[i][j] + " ");
         }
         System.out.println();
      }
   }
}

And the output will be like this:

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 

Two Dimensional Array in Data Structures || CseWorld online, in which elements are stored row by row is called as row majo rmatrix. Specifically, if you want to print a matrix or two-dimensional array but you don’t know the dimensions, you probably want to do something like the following: do, i = 1: m do, j = 1: n write (*,*) matrix (i, j) enddo enddo. Unfortunately, this will simply print all m*n numbers on separate lines because each write is followed by a newline.

Of course, you might swap the 7 & 5 as mentioned in other answers, to get 7 per row. //Displays a 2d array in the console, one line per row. static void  An array of arrays is known as 2D array. The two dimensional (2D) array in C programming is also known as matrix. A matrix can be represented as a table of rows and columns. Before we discuss more about two Dimensional array lets have a look at the following C program.

Following is a general way of printing 2D matrix such that every row is printed in separate lines. filter_none. edit close. play_arrow. link brightness_4 code  To print out the entire two dimensional array we can use python for loop as shown below. We use end of line to print out the values in different rows. When the above code is executed, it produces the following result − 11 12 5 2 15 6 10 10 8 12 5 12 15 8 6

In this post, we will see how to print them. 1. Arrays.toString(). We know that a two dimensional array in Java is a single-dimensional array having another single-  To process 2-dimensional array, you typically use nested loops. The first loop iterates through the row number, the second loop runs through the elements inside of a row. For example, that's how you display two-dimensional numerical list on the screen line by line, separating the numbers with spaces:

  • what's the problem with your print method?
  • Have you tried calling your print method?
  • Could it be because you are calling Arrays.deepToString(grid) instead of print(grid)?
