I have a PowerShell Command which I need to execute using Java program. Can somebody guide me how to do this?
My command is Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion, Publisher, InstallDate |
Format-Table –AutoSize

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\" ";
