goto语句一直被人所诟病，说它使得代码结构复杂化，但是语言设计者们还是没有放弃goto这个功能强大的语句。Java以面向对象所著称也没能够放弃goto，而是把它当做保留字，但是并未在语言中得到正式使用。 然而，从Java的break和continue这两个关键字的身上，我们依然能够看出一些goto的影子。 下面是《Thinking In Java 4th》中关于“goto”的介绍： 臭名昭著的“goto” goto 关键字很早就在程序设计语言中出现。事实上，goto 是汇编语言的程序控制结构的始祖：“若条件A，则跳到这里；否则跳到那里”。若阅读由几乎所有编译器生成的汇编代码，就会发现程序控制里包含了许多 跳转。然而，got 继续阅读 »
