How to print Two-Dimensional Array like table

You need to print a new line after each row... System.out.print("\n"), or use println, etc. As it stands you are just printing nothing - System.out.print(""), replace print with println or "" with "\n".


public class FormattedTablePrint {

    public static void printRow(int[] row) {
        for (int i : row) {
            System.out.print(i);
            System.out.print("\t");
        }
        System.out.println();
    }

    public static void main(String[] args) {
        int twoDm[][]= new int[7][5];
        int i,j,k=1;

        for(i=0;i<7;i++) {
            for(j=0;j<5;j++) {
                twoDm[i][j]=k;
                k++;
            }
        }

        for(int[] row : twoDm) {
            printRow(row);
        }
    }
}

Output

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  
31  32  33  34  35  

Of course, you might swap the 7 & 5 as mentioned in other answers, to get 7 per row.


If you don't mind the commas and the brackets you can simply use:

System.out.println(Arrays.deepToString(twoDm).replace("], ", "]\n"));
