Code Passion

Everyone should learn how to code, it teaches you how to think.

Why should I learn to code?

 My opinion is that learning how to code can help us to solve problems on our daily tasks, no matter what our job is or what hobbies we have. We really can turn our life simpler with little pieces of software that we consider usefull and share it with all the world. And this is each day easier, making the development a common knowledge and easier to learn.

 At this moment I'm mainly focused in proper learning how to code in Java and how to develop apps for Android OS.

Java
Principles Versions
There were five primary goals in the creation of the Java language:
  1. It must be "simple, object-oriented, and familiar".
  2. It must be "robust and secure".
  3. It must be "architecture-neutral and portable".
  4. It must execute with "high performance".
  5. It must be "interpreted, threaded, and dynamic"
As of 2015, only Java 8 is supported ("publicly"). Major release versions of Java, along with their release dates:
  • JDK 1.0 (January 21, 1996)
  • JDK 1.1 (February 19, 1997)
  • J2SE 1.2 (December 8, 1998)
