Android - THREAD Sections.

[Brian Alvarez]

This example also applies to JAVA compilations. In fact i will show the results in a java console window.

Tip: I have found that testing individual functions as Java console functions speeds up development, because
they compile much faster.

Here is the Java console output:



Note:
Usually you can work with the same data in the threads without crashes, but the results are unreliable,
it is recommended to work with a different data set (as in the example, where each thread works with a
different array index) to get reliable results. This also applies to using Database commands with threads.
It is not recommended to use GUI statements inside threads.

Thread sections are available only for Java and Android compilations.
