November 26, 2025 - We’ve made the assumption that the java command is available via the PATH variable · In this next example, we’re going to see how to modify the working environment. But before we do that let’s begin by taking a look at the kind of information we can find in the default environment: ProcessBuilder processBuilder = new ProcessBuilder(); Map<String, String> environment = processBuilder.environment(); environment.forEach((key, value) -> System.out.println(key + value));

Using that list, we've initialized a ProcessBuilder instance. Now using command() method, we've printed the underlying operating system command name and other details. package com.tutorialspoint; import java.util.ArrayList; import java.util.List; public class ProcessBuilderDemo { public static void main(String[] args) { // create a new list of arguments for our process List<String> list = new ArrayList<String>(); list.add("notepad.exe"); // create the process builder ProcessBuilder pb = new ProcessBuilder(list); // get the command list System.out.println(pb.command()); } }

January 20, 2026 - These modifications will be visible to subprocesses started via the start() method. Two ProcessBuilder instances always contain independent process environments, so changes to the returned map will never be reflected in any other ProcessBuilder instance or the values returned by System.getenv.

ProcessBuilder Class (Java.Lang) | Microsoft Learn
Modifying a process builder's attributes will affect processes subsequently started by that object's #start() method, but will never affect previously started processes or the Java process itself. Most error checking is performed by the #start() method. It is possible to modify the state of an object so that #start() will fail. For example, setting the command attribute to an empty list will not throw an exception unless #start() is invoked. <strong>Note that this class is not synchronized.</strong> If multiple threads access a ProcessBuilder instance concurrently, and at least one of the threads modifies one of the attributes structurally, it must be synchronized externally.

The Runtime.getRuntime().exec() approach is quite troublesome, as you'll find out shortly.
Take a look at the Apache Commons Exec project. It abstracts you way of a lot of the common problems associated with using the Runtime.getRuntime().exec() and ProcessBuilder API.
It's as simple as:
String line = "myCommand.exe";
CommandLine commandLine = CommandLine.parse(line);
DefaultExecutor executor = new DefaultExecutor();
executor.setExitValue(1);
int exitValue = executor.execute(commandLine);

Yes it is possible using ProcessBuilder.
ProcessBuilder example:
import java.io.*;
import java.util.*;
public class CmdProcessBuilder {
public static void main(String args[])
throws InterruptedException,IOException
{
List<String> command = new ArrayList<String>();
command.add(args[0]);
ProcessBuilder builder = new ProcessBuilder(command);
Map<String, String> environ = builder.environment();
final Process process = builder.start();
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
System.out.println("Program terminated!");
}
}
