I do not get this one in the java language.

I do not understand c[i].length and eg. c[2].length

and the third for loop.

/** multiplyMatrix multiplies two matrices and returns the result */
public static double[][] multiplyMatrix(double[][] a, double[][] b) {
double[][] c = new double[3][3];
for (int i
0; i < c.length; i++) {
for (int j = 0; j < c[i].length; j++) {
0; h < c.length; h++) {
for (int h
c[i][j] += a[i][h] * b[h][j];
}
}
}
return c;
