System.exit()方法内部调用exit() 方法的Runtimeclass.因此,调用System.exit(n)等效于调用:Runtime.getRuntime().exit(n). 这就是Java中的退出代码。 平均评分4.47/5。票数:55 谢谢阅读。 请使用我们的在线编译器使用 C、C++、Java、Python、JavaScript、C#、PHP 和许多更流行的编程语言在评论中发布代码。 像...
UseSystem.exit()method only when there is an unrecoverable error or condition and we need to exit the program immediately. Do not useSystem.exit()method for normal termination of the program. Use return statements or throw exceptions instead. Use meaningful and consistent exit codes to indicate ...

本案例通过java代码实现jvm规范中指令集和解释器,完成后就可以开始执行1到100的加和计算。 Java虚拟机顾名思义,就是一台虚拟的机器,而字节码(bytecode)就是运行在这台虚拟机器上的机器码。我们已经知道,每一个类或者接口都会被Java编译器编译成一个class文件,类或接口的方法信息就放在class文件的method_info结构中...

注:finally块语句唯一不执行的情况:异常处理代码catch中执行System.exit(1)退出Java虚拟机 ; 一段代码可能会发生多种类型的异常,当发生异常,会按顺序查看每个catch语句,并执行第一个与异常类型匹配的catch块,执行后,其他的catch语句将忽略,执行继续执行finally块,及异常块后的其他代码other code。

Java source code is compiled into intermediate byte-codes, which are then interpreted at run time by a platform-specific Java Virtual Machine (JVM). This is nice, because it allows developers to use any compiler they want on any platform to compile code, with the assumption that this ...
