在java 中退出程序,经常会使用System.exit(1) 或 System.exit(0). 查看System.exit()方法的源码,如下 /** * Terminates the currently running Java Virtual Machine. The * argument serves as a status code; by convention, a nonzero status * code indicates abnormal termination. * <p
查看java.lang.System的源码.我们能够看到System.exit()这种方法等价于Runtime.exit(),代码例如以下: /** * Terminates the currently running Java Virtual Machine. The * argument serves as a status code; by convention, a nonzero status * code indicates abnormal termination. * <p>
最近代码中常用的System.exit(),就来看看源码. 首先位于java.lang.System中,源码如下: /** * Terminates the currently running Java Virtual Machine. The * argument serves as a status code; by convention, a nonzero status * code indicates abnormal termination. 用来终止当前正在运行的JVM.参数用作状
关于RunTime类的介绍: /** * Every Java application has a single instance of class * <code>Runtime</code> that allows the application to interface with * the environment in which the application is running. The current * runtime can be obtained from t
2.解析 查看java.lang.System的源代码,我们可以找到System.exit(status)这个方法的说明,代码如下: /** * Terminates the currently running Java Virtual Machine. The * argument serves as a status code; by convention, a nonzero status * code indicates abnormal termination. * <p> * Th
