Goto是保留的，即使目前没有使用，但永远不要说永远:)

不，没有使用goto，但是您可以定义标签并留下一个到标签的循环。您可以使用break或continue后跟标签。所以你可以跳出多个循环层。看看教程。

Java中没有goto语句的原因可以在“Java语言环境”中找到:

Java has no goto statement. Studies illustrated that goto is (mis)used more often than not simply "because it's there". Eliminating goto led to a simplification of the language--there are no rules about the effects of a goto into the middle of a for statement, for example. Studies on approximately 100,000 lines of C code determined that roughly 90 percent of the goto statements were used purely to obtain the effect of breaking out of nested loops. As mentioned above, multi-level break and continue remove most of the need for goto statements.
