Java(版本7之前)不支持String switch.但是你可以通过使用一个来达到预期的效果enum.

private enum Mon {
   January,February,March,April,May,June,July,August,September,October,November,December
};

String value; // assume input
Mon mon = Mon.valueOf(value); // surround with try/catch

switch(mon) {
    case January:
        m=1;
        break;
    case February:
        m2;
        break;
    // etc...
}
