you can try to call the powershell.exe with some commands like :

String[] commandList = {"powershell.exe", "-Command", "dir"};  

        ProcessBuilder pb = new ProcessBuilder(commandList);  

        Process p = pb.start();

No need of reinvent the wheel. Now you can just use jPowerShell. (Disclosure: I am the author of this tool.)

String command = "Get-ItemProperty " +
                "HKLM:\\Software\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\* " +
                "| Select-Object DisplayName, DisplayVersion, Publisher, InstallDate " +
                "| Format-Table –AutoSize";

System.out.println(PowerShell.executeSingleCommand(command).getCommandOutput());

You can use -ExecutionPolicy RemoteSigned in the command.

String cmd = "cmd /c powershell -ExecutionPolicy RemoteSigned -noprofile -noninteractive C:\Users\File.ps1

You should write a java program like this, here is a sample based on Nirman's Tech Blog, the basic idea is to execute the command calling the PowerShell process like this:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class PowerShellCommand {

 public static void main(String[] args) throws IOException {

  //String command = "powershell.exe  your command";
  //Getting the version
  String command = "powershell.exe  $PSVersionTable.PSVersion";
  // Executing the command
  Process powerShellProcess = Runtime.getRuntime().exec(command);
  // Getting the results
  powerShellProcess.getOutputStream().close();
  String line;
  System.out.println("Standard Output:");
  BufferedReader stdout = new BufferedReader(new InputStreamReader(
    powerShellProcess.getInputStream()));
  while ((line = stdout.readLine()) != null) {
   System.out.println(line);
  }
  stdout.close();
  System.out.println("Standard Error:");
  BufferedReader stderr = new BufferedReader(new InputStreamReader(
    powerShellProcess.getErrorStream()));
  while ((line = stderr.readLine()) != null) {
   System.out.println(line);
  }
  stderr.close();
  System.out.println("Done");

 }

}

In order to execute a powershell script

String command = "powershell.exe  \"C:\\Pathtofile\\script.ps\" ";
