Pass parameter from array to powershell java program

Question

I have a java code that execute a powershell script.My parameters are in a string array that I got from user.

String sentence = clientinp.readUTF();
            String[] parts = sentence.split(",");

How should I put the parameters to the script every time I execute the code? I tried this code:

String command = "powershell.exe  $Add-DnsServerResourceRecordA -ZoneName -Name -IPv4Address -TimeToLive";

But I don't know how can I pass this array to powershell.What should I do?

If you have made sure that the input parameters are in the exact order you need them you can simply ask for the elements to do stuff like "powershell.exe $Add-DnsServerResourceRecordA" + parts[0] +" ... " + parts[...]; — px06

@Onkar I used this.now when i execute the powershell I want to pass my array instead of enter the value myself : String command = "powershell.exe $Add-DnsServerResourceRecordA -ZoneName -Name -IPv4Address -TimeToLive"; — sara

Use a ProcessBuilder. You have to put each parameter (including path to the program) as items to an array or list and pass it to the constructor of ProcessBuilder.

for example:

String[] arguments = {"powershell.exe", "$Add-DnsServerResourceRecordA", "-ZoneName", "[your zone name]", "-Name", "[your name]", "-IPv4Address", "[your ipv4 address]", "-TimeToLive", "[your TTL]"};
ProcessBuilder processBuilder = new ProcessBuilder(arguments);
Process process = processBuilder.start();

As an alternative you can use Runtime.getRuntime().exec()
