java的命令行参数到底怎么用，请给截图和实际的例子

8.2 命令行参数示例（实验）
public class Test {
public static void main(String[] args){
        if(args.length==0){
               System.out.println("you don‘t set command line parameters!");
        }else{
               for (int i=0; i
                     System.out.println("args[" + i + "] is: " + args[i]);
            }
       }
}
}

when use eclipse, don‘t "run as application",directly use "run configurations/run", then add in aguments in program arguments.（当运行eclipse，不要"run as application"，而直接用"run configurations/run"，然后加上参数在，program arguments.）
