推荐答案

Java 小程序具有生命周期方法.它们是 init、start、stop 和 destroy.您应该学会使用它们，但更重要的是，您应该了解浏览器何时调用每个方法.

Java applets have lifecycle methods. Those are init, start, stop and destroy. You should learn to use them, but what's more important, you should learn when a browser calls each of this method.

当您离开页面时，会调用 stop 并且您应该停止在 start 中启动的线程并清理资源(如果您分配了任何资源).浏览器不会在每个页面重新加载时杀死 JVM，因为它会非常低效(以及其他原因)，因此如果您想停止小程序正在执行的任何操作，请在 stop 方法中实现它.

When you navigate away from your page, stop is called and you should stop threads you started in start and cleanup resources if you allocated any. Browsers do not kill JVM on every page reload because it would by extremely inefficient (and for other reasons), so if you want to stop whatever your applet is doing, implement it in stop method.
