在启动Java控制台应用程序,可以一次性地向程序中传递零至多个参数,这些参数被称为命令行参数(Command Line Arguments),这些参数将被系统接收并静态初始化为一个一维的String数组对象,然后将该数组对象作为实参传给应用程序入口main(),其语法格式为: java <应用程序类名>[<命令行参数>]* 1. 简单的测试程序如下: p...
所有参数都从Argument实例作为String检索(没有类型的参数)。 jClap JAR还包含一个“样本”应用程序( SampleArguments.class ),IDE反编译器(例如IntelliJ IDEA的内置反编译器和Eclipse的Enhanced Class Decompiler )可以反编译以查看可以写入的源代码类型。使用jClap。 jClap是一个小型易用的库,用于处理Java的命令行参数...

用eclipse运行Java时输入command line argument：在要运行的类上右键点击Run As-->Run Configurations...在弹出界面中点击Arguments 然后弹出如下界面：1.其中Program arguments栏里可以输入程序运行所需的参数，也就是main方法的参数，如果参数为多个，则用空格分开。2.VM arguments里接收的是系统变量参数，...
The command-line arguments in Java allow us to pass arguments during the execution of the program. As the name suggests arguments are passed through the command line. Example: Command-Line Arguments class Main { public static void main(String[] args) { System.out.println("Command-Line argument...
A Java application can accept any number of arguments from the command line. This allows the user to specify configuration information when the application is launched. The user enters command-line arguments when invoking the application and specifies them after the name of the class to be run. ...
2. Accessing Command-Line Arguments in Java Since the main method is the entry point of a Java application, the JVM passes the command-line arguments through its arguments. The traditional way is to use a String array: public static void main(String[] args) { // handle arguments } However...
The program arguments passed at launching the Java program are called command line arguments in form of -- $ java MyClass arg1 arg2 arg3 arg4 arg5.
后来又找到一个CommandLineArgumentParser类库,http://commandlinearguments.codeplex.com/,但文档不多。 后来又发现 The Apache Commons CLI 类库,它可以处理各种命令行参数,可惜是个JAVA类库。 下面2个地方有相关介绍: http://commons.apache.org/cli/usage.html ...
