My problem is simplest what you think. I am writing two method:
xlswrite(...) and xlsread(...)
The first works well while the second no.
My exercise is this:
*1)* To build a simple matrix:
int columns = 100;
int rows = 100000;
Object[][] matrix = new Object[rows][columns];
for (int j = 0; j < rows; j++) {
for (int k = 0; k < columns; k++) {
matrix[j][k] = j - k;
}
}
*2)* To build 2 methods with these specifications
xlswrite("filename.xlsx",matrix);
Object[][] matrix2 = xlsread("filename.xlsx");
*3)* It must be worth the following mathematical relationship:
matrix = matrix2
I just created xlsread() and it works but it can not read filename.xlsx
because it is too big file.
I used your example code:
public class ExampleEventUserModel {...}
but it doesn't work and I can not find xercesImpl.jar!
