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
Activity.finish() Calling this method will let the system know that the programmer wants the current Activity to be finished. And hence, it calls up onDestroy() after that. The system will remove the top level activity from stack when calling finish(
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
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
public class test { public static void main(String[] args) { try { System.exit(0); System.out.println("hello"); } finally { System.out.println("In the finally block"); } } } System.exit(0)会跳过finally块的执行,什么都不输出.
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
