利用《<代码>return, Java代码中的关键词将恢复执行,使之达到“呼号”中最后一项呼吁代码。 如果物体foo,baz.bar(),return <代码>bar方法的关键词将继续在<代码>foo上执行。
请允许我表示,我反对以下文字:foofoofoo,在以上设想中打上foofoofoo, 以及foofoofoo 电话:baz.bar()。 Java是否使用<代码>return 关键词或其它东西,以便bar中的代码。 这种方法能够将所有回路退回到foo?
(成果)
无,是不可能的。 你们不得不在一定时间用代码处理这一紧急情况(一种例外做法是,它只是自动增加一个轨道)。
然而,这样做可能不是一个好的想法。 假设你突然需要从<条码>上打
完全与这一职务的正确工具相仿的一个例外:baz.bar(>,t care that it has to go to foo, 它应当知道已经发生了什么事情foo。 应当知道,这种特殊情况会发生并处理(即使它只是做不到这一点)。 如果它要避免在任何事情上添加一个 throw条款,则使用不受约束的例外。
幸运的是,在 Java是不可能的。
很少出现类似情况,例如,当你在工作环境上转而把工作推向一个协调员小组时。
但是,在应用方案中绝对是错误的。
我不是一幅巨大的 Java笑,因此我可以肯定地说,但这不是一件安全的事情,我怀疑这一点将在 Java得到支持。
现在正是这一C/C++,你可以做一个小的黑板,将压倒 st的返回地址。
