inexpensive jsp apache This is quite common in code that uses arrays.Two Dimensional Arrays The most common kind of multidimensional array is a two-dimensional array. If you think of a one-dimensional array as a column of values you can think of a two-dimensional array as a table of values like so: c0 c1 c2 c3 r0 0 1 2 3 r1 1 2 3 4 r2 2 3 4 5 r3 3 4 5 6 r4 4 5 6 7 Here we have an array with five rows and four columns. It has twenty total elements. However we say it has dimension four by five, not dimension twenty.

These are the element's row and column positions. For instance if the above array is called J then J[0][0] is 0, J[0][1] is 1, J[0][2] is 2, J[0][3] is 3, J[1][0] is 1, and so on.Here's how the elements in a four by five array called M are referred to: M[0][0]M[0][1]M[0][2]M[0][3]M[0][4] M[1][0]M[1][1]M[1][2]M[1][3]M[1][4] M[2][0]M[2][1]M[2][2]M[2][3]M[2][4] M[3][0]M[3][1]M[3][2]M[3][3]M[3][4] Declaring, Allocating and Initializing Two Dimensional ArraysTwo dimensional arrays are declared, allocated and initialized much like one dimensional arrays. However we have to specify two dimensions rather than one, and we typically use two nested for loops to fill the array.

Here's some code that would create and fill such an array:class FillArray { public static void main (String args[]) { int[][] M; M = new int[4][5]; for (int row=0; row < 4; row++) { for (int col=0; col < 5; col++) { M[row][col] = row+col; } } } }Of course the algorithm you would use to fill the array depends completely on the use to which the array is to be put. Here is a program which calculates the identity matrix for a given dimension. The identity matrix of dimension N is a square matrix which contains ones along the diagonal and zeros in all other positions.class IDMatrix { public static void main (String args[]) { double[][] ID; ID = new double[4][4]; for (int row=0; row < 4; row++) { for (int col=0; col < 4; col++) { if (row != col) { ID[row][col]=0.
