[command-line] How do you input command line arguments in IntelliJ IDEA?

I usually input command line arguments in Eclipse via run configuration. But I don't know how do achieve the same task in IntelliJ IDEA.

In IntelliJ, if you want to pass args parameters to the main method.

go to-> edit configurations

program arguments: 5 10 25

you need to pass the arguments through space separated and click apply and save.

now run the program if you print

System.out.println(args[0]); System.out.println(args[1]); System.out.println(args[2]); Out put is 5 10 25

Do this steps :-

Go to Run - Edit Configuration -> Application (on the left of the panel ) -> select the scala application that u want to run -> program argument

To do this in IntelliJ IDEA 2020.2.3 (Community edition) on Windows 10:

1. ALT-SHIFT-F10
2. 0
3. [TAB] 7 times

Updated for 11/2020.

We cannot go into Terminal and give in the good old java Classname arg1 arg2 arg3

We'll have to edit the run configuration.

Step 1 : Take the Run menu
Step 2 : Select Edit Configurations
Step 3 : Fill the Program arguments field

After that, the arguments will be inserted to the end of the command that IntelliJ creates whenever you run the program :)

You separate multiple program arguments with spaces. (this was not obvious to me)

Program arguments:Julia 52 Actress

If you are using intellij go to Run > Edit Configurations menu setting. A dialog box will appear. Now you can add arguments to the Program arguments input field.

There's an "edit configurations" item on the Run menu, and on the pull-down to the left of the two green "run" and "debug" arrows on the toolbar. In that panel, you create a configuration with the "+" button in the top left, and then you can choose the Class containing main(), add VM parameters and command-line args, specify the working directory and any environment variables.

There are other options there as well: code coverage, logging, build, JRE, etc.

On a MacBook Air with "OSX 10.11.3":

1. ctrl + alt + r
2. e
3. Enter
4. Program arguments: Write your command line parameters (space between each item if you have more than one argument)
5. Enter

Windows, Linux, some Macs:

ALT+SHIFT+F10, Right, E, Enter, Tab, enter your command line parameters, Enter. ;-)

Mac with "OS X 10.5" key schema:

CTRL+ALT+R, Right, E, Enter, Tab, enter your command line parameters, Enter.

Example I have a class Test:

Then. Go to config to run class Test:

Step 1: Add Application

Step 2:

You can input arguments in the Program Arguments textbox.

Main Program -> Run -> Edit Configurations -> Inside Configuration there is Program arguments text box. add space separated argument in the text box. Then you can read those arguments in the args array (public static void main(String[] args))

As @EastOcean said, We can add it by choosing Run/Debug configurations option. In my case, I have to set configuration for junit. So on clicking Edit configurations option, a pop up window is displayed. Then followed the below steps:

1. Click on + icon
2. Choose junit from the list
3. Then we can see Configuration tab in the right hand side
4. Select test kind, in my case Its a Class
5. Next step browse through the location of the class which needs to be executed/run
6. Next to that, choose VM Option, click on expand arrow icons
7. Set required arguments for an example (-Durl="http://test.com/home" -Dsourcename="API" -Dbrowsername="chrome")
8. Set jre path.

Save and run.

Thank you.

maytham-???i???, you can use this code to simulate input of file:

System.setIn(new FileInputStream("FILE_NAME"));

Or send file name as parameter and then put it into FileInputStream:

System.setIn(new FileInputStream(args[0]));
