    <p>If you want to get the rows, you need to get the values from each array, then create a new array from the values. You can assign the values manually, or use a for-loop, such as this...</p> <pre><code>int[][] MyMat = {{0,1,2,3,4}, {9,8,7,6,5}}; // get your columns... (easy) int[] My0= MyMat[0]; //My0 = {0,1,2,3,4} int[] My1= MyMat[1]; //My1 = {9,8,7,6,5} // get the rows... (manually) int[] My_0= new int[]{MyMat[0][0],MyMat[1][0]}; //My_0 = {0,9} int[] My_1= new int[]{MyMat[0][1],MyMat[1][1]}; //My_1 = {1,8} int[] My_2= new int[]{MyMat[0][2],MyMat[1][2]}; //My_2 = {2,7} int[] My_3= new int[]{MyMat[0][3],MyMat[1][3]}; //My_3 = {3,6} int[] My_4= new int[]{MyMat[0][4],MyMat[1][4]}; //My_4 = {4,5} // get the rows... (as a for-loop) int size = MyMat.length; int[] My_0 = new int[size]; //My_0 = {0,9} int[] My_1 = new int[size]; //My_1 = {1,8} int[] My_2 = new int[size]; //My_2 = {2,7} int[] My_3 = new int[size]; //My_3 = {3,6} int[] My_4 = new int[size]; //My_4 = {4,5} for (int i=0;i&lt;size;i++){ My_0[i] = MyMat[i][0]; My_1[i] = MyMat[i][1]; My_2[i] = MyMat[i][2]; My_3[i] = MyMat[i][3]; My_4[i] = MyMat[i][4]; } </code></pre> <p>Otherwise, turn your entire array around so that it stores <code>{row,column}</code> instead of <code>{column,row}</code>, like this...</p> <pre><code>int[][] MyMat = {{0,9},{1,8},{2,7},{3,6},{4,5}}; // get the rows... (easy) int[] My_0= MyMat[0]; //My_0 = {0,9} int[] My_1= MyMat[1]; //My_1 = {1,8} int[] My_2= MyMat[2]; //My_2 = {2,7} int[] My_3= MyMat[3]; //My_3 = {3,6} int[] My_4= MyMat[4]; //My_4 = {4,5} // get the columns... (manually) int[] My0= new int[]{MyMat[0][0],MyMat[1][0],MyMat[2][0],MyMat[3][0],MyMat[4][0]}; //My0 = {0,1,2,3,4} int[] My1= new int[]{MyMat[0][1],MyMat[1][1],MyMat[2][1],MyMat[3][1],MyMat[4][1]}; //My1 = {9,8,7,6,5} // get the columns... (as a for-loop) int size = MyMat.length; int[] My0 = new int[size]; //My0 = {0,1,2,3,4} int[] My1 = new int[size]; //My1 = {9,8,7,6,5} for (int i=0;i&lt;size;i++){ My0[i] = MyMat[0][i]; My1[i] = MyMat[1][i]; } </code></pre> <p>Note that it isn't possible to have a shorthand that will allow you to get both the rows and the columns easily - you'll have to decide which you want more, and structure the arrays to be in that format.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
