• Contributions in the tutorial category should be unique and non-simple to really add value to the community. Transposition of a matrix is a mathematical concept instead of a technical aspect of the specified project, Java.

Suggestions:

• You can provide tutorials about technical instructions directly related with Java, instead of code examples, in your future contributions.
