These are the files to aid enforcement of coding conventions, both by enabling the IDE (Eclipse) to format code accordingly and to configure the CheckStyle tool to audit the code accordingly.

Note that my indenting of braces is somewhat non-standard. I use it and like it because it is more self-consistent than other indentation schemes. The key difference is that I align the closing brace with the block it encloses, e.g:

if( expression) {
  block1;
  }
else {
  block2;
  }
more code;

The main point being that you can run your eye down a column and see immediately the line of execution. If also allows a whole sequence of if / else if expressions to line up nicely, as can switch / case commands and class and method definitions.

Your mileage may vary, as the saying goes. Clearly, take what you like out of these settings and change what you do not!
