How to Invoke Executables with Parameters and Handle Paths Containing Spaces in Java?

Invoking Executables with Parameters and Handling Paths with Spaces

In this article, we explore the challenge of invoking executables using Java's ProcessBuilder and passing in desired parameters.

Initially, the provided code snippet successfully launches an executable. However, to pass parameters, you must specify them as arguments within the ProcessBuilder constructor:

<code class="java">Process process = new ProcessBuilder("C:\PathToExe\MyExe.exe", "param1", "param2").start();</code>

Additionally, the code snippet struggles with paths containing spaces. To address this, you can use the ProcessBuilder's command() method, which accepts an array of commands and handles spaces appropriately:

<code class="java">Process process = new ProcessBuilder().command("C:\Path\To\Exe\MyExe.exe", "param1", "param2").start();</code>

This approach ensures that spaces in the path are correctly interpreted and the executable is launched as intended. By leveraging these techniques, you can effectively invoke executables and pass in parameters, even in scenarios where the paths contain spaces.
