Java user.dir: Set Working Directory

In a Java program, you can set system properties using the System.setProperty() method. To set the user.dir property, you can use the following code:

System.setProperty("user.dir", "your/directory/path");

This way, you can set the user.dir property to a specific path. Please note that this method will only take effect during the program’s runtime and will not permanently change the operating system’s properties.
