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
在使用TestNG做单元测试时,需要测试的代码中出现System.exit(0),导致单元测试还未结束程序就停止了.解决方法如下: public class TestMain { public static void main(String args[]) { NoExitSecurityManager manager = new NoExitSecurityManager(); System.setSecurityManager(manager); new TestNGApp("test/Te
参考:http://www.cnblogs.com/xwdreamer/archive/2011/01/07/2297045.html System.exit(int status) 方法 java.lang.System的源代码 /** * Terminates the currently running Java Virtual Machine. The * argument serves as a status code; by convention, a nonzero status
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>
java程序中为了程序正常运行,需要给无限循环加入一个退出选项,保证程序的可执行性. import java.util.Scanner; public class { public static void main(String[] args) { Scanner scan = new Scanner(System.in); system.out.println("请输入您的操作选项"); int num = scan.nextInt(); switch (num) { case '1
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
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
方法源码: /** * Terminates the currently running Java Virtual Machine. The * argument serves as a status code; by convention, a nonzero status * code indicates abnormal termination. * <p> * This method calls the <code>exit</code> method in c
android Activity类中的finish().onDestory()和System.exit(0) 三者的区别 Activity.finish() Call this when your activity is done and should be closed. 在你的activity动作完成的时候,或者Activity需要关闭的时候,调用此方法. 当你调用此方法的时候,系统只是将最上面的Activity移出了栈,并没有及时的调用onDestory()方法,其占用的资源也没有被及时释
