8 Best Java Compiler Apps for Android & iOS

Today programming is a very popular hobby. It is no surprise, as coding develops logical thinking and problem-solving.

What is more, Java works according to the principle called ‘write once, run anywhere’. So if you have written your code, it will work on every device that supports Java. Isn’t it great? You will never need to recompile, just use the code you have. Every Java Virtual Machine will understand it easily.
