如何动态地将命令行参数传递给主方法

Question

I am passing my main class as a command line argument to launch VM

    VirtualMachineManager manager = Bootstrap.virtualMachineManager();
    LaunchingConnector connector = manager.defaultConnector();
    Map arguments = connector.defaultArguments();
    ((Connector.Argument)arguments.get("options")).setValue(userVMArgs);
    ((Connector.Argument)arguments.get("main")).setValue(cmdLine);

Answer 1

If you want to launch VM by sending arguments, you should send VM arguments and not Program arguments.

java -DsysProp1=sp1 -DsysProp2=sp2 test.ArgsTest pro1 pro2 pro3

Answer 2

Run ---> Debug Configuration ---> YourConfiguration ---> Arguments tab

Answer 3

We can pass string value to main method as argument without using commandline argument concept in java through Netbean<\/em>

 package MainClass;
 import java.util.Scanner;
 public class CmdLineArgDemo {

static{
 Scanner readData = new Scanner(System.in);   
 System.out.println("Enter any string :");
 String str = readData.nextLine();
 String [] str1 = str.split(" ");
 // System.out.println(str1.length);
 CmdLineArgDemo.main(str1);
}  

   public static void main(String [] args){
      for(int i = 0 ; i<args.length;i++) {
        System.out.print(args[i]+" ");
      }
    }
  }

转到运行配置并在参数选项卡中，您可以编写参数
