Learn Java¶

Learning Java is not something to be afraid of. A good programmer is a good programmer in any language.

If you are currently a 4GL developer, you will find that Java has a very concise syntax (less than 60 keywords!) that can be learned in less than 3 days. The real effort in learning Java is in two areas:

• Application design and development is done using an Object Oriented development model. It may take a few months and some mistakes in writing real code to get comfortable.
• Although Java has a small and regular syntax, it contains a very large set of libraries that are built into the standard distribution of the language. Doing real work normally requires extensive use of these libraries. Learning where to look for functionality and learning how to use these available features, will take some time.
