For some applications that access the date a lot, it can help to set the local timezone to be GMT, so that no conversion has to take place. Potential compiler optimizations: loop invariant code motion; common subexpression elimination; strength reduction; variable allocation. Don't turn off na...
These variables differ from their normal counterparts in that eachthread that accesses one (via itsget orset method) has itsown, independently initialized copy of the variable.ThreadLocal instances are typically privatestatic fields For example, the class belowgenerates unique identifiers local to each...
