如何在 powershell 脚本中为 java 程序传递用户输入

Question

I have a java program abc.java which prompts the user for some input. Now I am calling this java file in my powershell script. When I am executing the powershell, it comes to the prompt for the input. So now how can I enter the user input here?

My powershell script is as follows:

cd 'C:\LDAP\test1'
java abc

The output of the above run is as follows:

PS C:\> C:\LDAP\sample.ps1
Enter the prefix:

Now how to enter the value? I am ok with either entering the input during the runtime or even hardcode the input in the powershell script.

System.out.println("Enter the prefix:"); 

String strPrefix = objScanner.nextLine(); 

System.out.println("Enter the Country:"); 

String strLocation = objScanner.nextLine();

Answer 1

I wrote abc.java like this.

import java.util.Scanner;        

class abc {
    public static void main(String[] args) {
        try {
            Scanner objScanner = new Scanner(System.in);
            System.out.print("Enter the prefix:"); 
            String strPrefix = objScanner.nextLine(); 
            System.out.println("Prefix is \"" + strPrefix + "\"");

            System.out.print("Enter the Country:"); 
            String strLocation = objScanner.nextLine();
            System.out.println("Country is \"" + strLocation + "\"");
        } catch(Exception e) {
            e.printStackTrace();
        }
    }
}

And my powershell seems as follows.

PS C:\> C:\LDAP\sample.ps1
Enter the prefix:Mr
Prefix is "Mr"
Enter the Country:America
Country is "America"

If you use

System.out.println("Enter the prefix:"); 

and

System.out.println("Enter the Country:"); 

,powershell seems as follows.

PS C:\> C:\LDAP\sample.ps1
Enter the prefix:
Mr
Prefix is "Mr"
Enter the Country:
America
Country is "America"
