Two dimensional array in Java

Question

I'm trying to make a two dimensional array and output the results [3][3] in 3 lines and 3 colons, but I get it like 123456789 in a straight line. Now I know that I get this result because of the "println" command but I would like to know how can I get it work the way I want it to. Sorry, I'm new to programming.

 import java.util.Scanner; public class klasa { public static Scanner lexo = new Scanner(System.in); public static void main(String[]args){ int[][] array = new int[3][3]; for(int a=0;a<3;a++){ for(int b=0;b<3;b++){ System.out.println("Shkruaj numrat: "); array[a][b]= lexo.nextInt(); } } for(int a =0; a<3;a++){ for(int b=0;b<3;b++){ System.out.println(array[a][b]); } } } }

Then the answers you have will do it - just get rid of the spaces. — Alan Stokes

You should try:

for(int a = 0; a < 3;a++){ for(int b = 0; b < 3;b++){ System.out.print(array[a][b] + " "); } System.out.println(); //new line }

to make a new line only after three elements (and add spaces (optional)).

Hope this helps.

 for(int a = 0; a<3; a++){ for(int b=0; b<3; b++){ System.out.print(array[a][b]); System.out.print(" "); } System.out.println(); }

(That prints trailing spaces on each line, but it's a decent start.)

Use plain old print for each value, then print a newline after each row in your outer loop.

In general make your code reflect precisely what you are trying to do: Print each element in a row, followed by a newline. The computer generally follows your instructions to the letter.
