Java Explicit Declaration in Multi Dimensional arrays

Question

I am trying to explicitly declare values in a multidimensional array. I keep getting a multitude of error messages

Here is the offending code:

    int[][] test = new int [6][3];
    test[0] = {1,2,3};
    test[1] = {1,3,2};
    test[2] = {2,3,1};
    test[3] = {2,1,3};
    test[4] = {3,2,1};
    test[5] = {3,1,2};

Is this not allowed in 2 dimensional arrays?
I have read the java doc on arrays

error ']' expected, error: illegal start of expressions, error illegal start of expression and error not a statement for the 2nd line — Zhv Z

int [][] test = {
        {1,2,3},
        {1,3,2},
        {2,3,1},
        {2,1,3},
        {3,2,1},
        {3,1,2}};

You had wrong syntax. You have to specify what to instantize.

int[][] test = new int [6][3];
test[0] = new int[]{1,2,3};
test[1] = new int[]{1,3,2};
test[2] = new int[]{2,3,1};
test[3] = new int[]{2,1,3};
test[4] = new int[]{3,2,1};
test[5] = new int[]{3,1,2};

Thanks Milan, I've spend an inordinately large amount of time on this problem

Additionally if the OP does it this way, they do not need to initialize the second dimension of the array as [3]. They can initialize the array to new int[6][] as the receding lines initialize those elements.
