SBCCS - Supply Break or Comment in Case Statement

According to Sun Code Conventions for Java, every time a case falls through (doesn't include a break statement), a comment should be added where the break statement would normally be. The break in the default case is redundant, but it prevents a fall-through error if later another case is added.

Wrong

switch( c ) {
    case 'n':
        result += '\n';
        break;
    case 'r':
        result += '\r';
        break;
    case '\'':
        someFlag = true;
    case '\"':
        result += c;
        break;
    // some more code...
}

Tip: Add /* falls through */ comment where the break statement would normally be.

Right

switch( c ) {
    case 'n':
        result += '\n';
        break;
    case 'r':
        result += '\r';
        break;
    case '\'':
        someFlag = true;
        /* falls through */;
    case '\"':
        result += c;
        break;
    // some more code...
}
