I have experience in doing Java software tool for my work projects with my employer.
For this project, i have created the sample program. The GUI uses JTable (2 of them) for the matrix where data can be copy and paste over from text and delimited by space,comma or tabs. The console will parse the input into text below:
var data1[][] =
{
{ 1, 2, 3, 4 },
{ 5, 6, 7, 8 },
{ 9, 10, 11, 12 },
{ 13, 14, 15, 16 },
{ 17, 18, 19, 20 },
};
//***************************************************************
var data2[][] =
{
{ 1, 2, 3, 4 },
{ 5, 6, 7, 8 },
{ 9, 10, 11, 12 },
{ 13, 14, 15, 16 },
{ 17, 18, 19, 20 },
};
Please do contact me if you are interested.
