The Need for Inter-thread SignalingThrough synchronization, one thread can safely change values that another thread will read. How does the second thread know that the values have changed? What if the second thread is waiting for the values to
Missed NotificationA missed notification occurs when threadB tries to notify threadA, but threadA is not yet waiting for the notification. In a multithreaded environment like Java, you don’t have much control over which thread runs and for how long.

使用Java語言編寫應用程式最大的優點在於“一次編譯,處處運行”,然而這並不是說所有的Java程式都具有跨平台的特性,事實上,相當一部分的Java程式是不能在別的作業系統上正確啟動並執行,那麼如何才能編寫一個真正的跨平台的Java程式呢?下面是在編寫跨平台的Java程式是需要注意的一些事情:1、編寫Java跨平台應用程式時,你可以選擇JDK1.0,1.1,1.2或支援它們的GUI開發工具如:Jbuilder,Visual Age for Java
