• Apache Streams Code Conventions

The Apache Streams code should follow our code conventions. All code which is contributed to the project should adhere to these guidelines.

• 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 140 characters. For wrapped lines use an indent of 4 characters.
• Within a class or interface, definitions should be ordered as follows:
  • Class (static) variables
  • Instance variables
  • Constructors
  • Methods
  • Inner classes (or interfaces)

• Do not use ’’ package imports (for example import org.apache.streams.)

• For other cases, we try to follow Java code conventions as much as possible.
