OOP Principles For The Java Designer
Here are some useful information which should be familiar with all the java programmers/designers :
1. DRY
DRY stands for Don’t Repeat Yourself, which is pretty self explanatory. This means that you shouldn’t be duplicating your code in a program. If a code fragment is appearing in two places, then you would do well to turn it into a method instead of writing the entire fragment again. Lack of duplication helps in easy maintenance of the code.
2. Encapsulation
Whether your project gets bought over or whether you work on it yourself, your code will always change. So, it is good to encapsulate the part of the code that you think will be changed. This makes you code easy to maintain and test.

Hi All,
If you are thinking to create own custom portlet mode with liferay and want to show in configuration wrench button, then its not OOB available with Liferay and cannot achieve using simply configuration.
Liferay supports below modes :
If you are thinking to create own custom portlet mode with liferay and want to show in configuration wrench button, then its not OOB available with Liferay and cannot achieve using simply configuration.
Liferay supports below modes :
- about
- config
- edit
- editDefaults
- editGuest
- help
- preview
- view
But below tag is making bit confusion whether it's support of custom mode or not. So this is used for Liferay custom modes(editDefault,editGuest etc.) only.
<custom-portlet-mode><portlet-mode>edit_guest</portlet-mode><portal-managed>true</portal-managed></custom-portlet-mode>
