Java's etymological construction lacks control stream elucidation, as shown by the "goto" statement. In this part, we'll look at why Java doesn't have a goto function, some of its options, and how to use them to achieve similar goals. Syntax First, let's examine Java's language ...

然而,Python提供了一些替代方案来实现类似的功能。例如,你可以使用循环(如for循环、while循环)和条件语句(如if语句)来控制代码的执行流程。如果你需要在代码中跳转到某个特定的位置,可以使用函数(function)来实现。将相关的代码封装到一个函数中,然后通过调用该函数来实现类似goto的跳转效果。

Java语言中goto是保留关键字,没有goto语句,也没有任何使用goto关键字的地方。 Java中也可在特定情况下,通过特定的手段,来实现goto的功能。显然Java不愿意开发者随意跳转程序。下面解释两个特定: 特定情况:只有在循环体内,比如for、while语句(含do...while语句)中。 特定手段:语句标签和循环控制关键字bre javas实...
