Today programming is a very popular hobby. It is no surprise, as coding develops logical thinking and problem-solving.
Some people take up learning Java as a first programming language. This is quite reasonable because many mobile applications and sites are written in Java. This language is constantly developing, this is why it is so popular and widely respected.
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.
