How to create a simple 4 in Java × 3 two dimensional array?

I already know it in C, but Java is more challenging for me This is what I have I just want it to have 4 rows and 3 columns initialized to 1 - 12 and print it to the screen Is my mistake obvious to you? thank you!

I got 13 errors:（

Code I tried:

import java.util.*;


class twoDimensional array
{ public static void main(String args[])
{
int[][] twoDArray = new int[4][3];

twoDArray[][]={{1,2,3},{4,5,6},{7,8,9},{10,11,12}};

System.out.print(twoDArray.toString);


}
}

Solution

First, arrays (even 2D arrays) do not overwrite object toString. You can use arrays Deeptostring (object []) and initialize the array at declaration time It's like

int[][] twoDArray = new int[][] { 
        { 1,3 },{ 4,6 },{ 7,9 },{ 10,12 } 
};
System.out.println(Arrays.deepToString(twoDArray));
