To improve the readability and maintainability of the Apache UIMA™ code, we have adopted the following code conventions. All UIMA developers should adhere to these guidelines when committing changes or submitting patches.

• Use 2 spaces for indentation. No tabs!
• Place open braces on the same line as the declaration, for example:

  		  public class Foo extends Bar {
  		    public static void main(String args[]) {
  		      try {
  		        for (int i = 0; i < args.length; i++) {
  		          System.out.println(Integer.parseInt(args[i]));
  		        }		        
  		      }
  		      catch(NumberFormatException e) {
  		        e.printStackTrace();
  		      }
  		    }
  		  }		  
  	  

• Wrap lines longer than 100 characters. For wrapped lines, either use an indent of 8 characters or align with the expression at the same level on the previous line.
• Within a class or interface, definitions should be ordered as follows:
  1. Class (static) variables
  2. Instance variables
  3. Constructors
  4. Methods
• Do not use package imports (for example import org.apache.uima.*)
• For other cases, we try to follow Sun's code conventions as much as possible: see https://java.sun.com/docs/codeconv
