Java Coding Style
Java Code shall be formatted according Code Conventions for the Java Programming Language by Sun Microsystems, Inc.
Additional, indententation shall be done by (4)spaces, instead of tabs.
Eclipse 3.2 - and I guess also other Java IDEs - provides a Code Formatter option according the Java Convention by Sun. You may import the Eclipse Code Formatter Profile Java Conventions without tabs, which differs from Eclipse's build-in Java Convention Formatter Profile only by the Indentation Tab policy modified from Mixed to Spaces only.
