System.exit(int)可以扔一个SecurityException。如果发生这种情况,将执行finally块。并且由于相同的主体从相同的代码库调用相同的方法SecurityException,因此第二次调用可能会抛出另一个。这是第二种情况的示例:import java.security.Permission;public class Main{ public static void main(String... argv) ...
问Java的System.exit()如何处理try/catch/finally块？EN不是的。System.exit(0)不会返回，也不会执行...
publicclasstest {publicstaticvoidmain(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。
Java | try-catch-finally-return执行顺序 1. try中没有抛出异常,try、catch和finally块中都有return语句 运行结果: 执行顺序:执行try块,执行到return语句时,先执行return的语句,--i,但是不返回到main方法,执行finally块,遇到finally块中的return语句,执行--i,并将值返回到main方法,这里就不会再回去返回try块中...
invoke(); // make sure, we enter the catch block if the task leaves the invoke() method due // to the fact that it has been canceled if (isCanceledOrFailed()) { throw new CancelTaskException(); } // --- // finalization of a successful execution // --- // fini...
If You Put System.exit(0) on Try or Catch block, Will Finally Block Execute? JVM platform dependent? Method overriding vs overloading Why have a private constructor Difference between object and class How copy constructors work Final modifier Finally block Java: Will Finally run after ...
A side-note for the use of exit with finally: if you exit somewhere in a try block, the finally won't be executed. Could not sound obvious: for instance in Java you never issue an exit, at least a return in your controller; in PHP instead you could find yourself exiting from a con...
这个想法是，它使构建需要执行一些“清理”代码的代码变得容易（将其视为try-finally块）。一个有用的...
try { BufferedReader br = new BufferedReader(new FileReader("file.txt")); System.out.println(br.readLine()); br.close(); } catch (IOException e) { System.exit(2); } finally { System.out.println("Exiting the program"); } Here, we must note that the finally block does not get exe...
在java中使用finally子句返回try/catch块 、、、 在java中给定以下try/catch块: return;catch(SomeException e){} System.out.println("This is the finally block");根据这篇文章:"“我可以看到程序的输出将是'This is the finally block‘。但是,我不知道这是怎么回事,因为print语句前面有一个return…… ...
