Java Programming Style Guide

Line Length

Avoid lines longer than 80 characters When an expression will not fit on a single line of 80 characters, break it according to these general principles:

Break after a comma.
Break before an operator.
Align the new line with the beginning of the expression at the same level on the previous line.

someMethod(longExpression1, longExpression2, longExpression3, 
           longExpression4, longExpression5);
           
longName1 = longName2 * (longName3 + longName4 - longName5)
            + 4 * longname6;

Rationale

Lines longer than 80 characters wrap around in the source code printout, making your code harder to read and understand.
