And now other Template to build Extension: (Copy, Paste and Study: Plantilla2.java file)

If you want to start building extensions, I recommend you start with mathematical functions, for example multiply two numbers, calculate the body mass index (BMI), obtain a random number, calculate the area of a triangle, calculate the volume of a cylinder, …

When you know how to perform these mathematical functions, you can launch yourself to learn a bit of Java and write more complicated extensions.

Regards.
