Question

How can you create a directory anywhere on your hard drive using Java? For Example, I would like to create a folder in the home folder of the computer. If I use this code:

File file = new File("~/test");
if (!file.exists()) {
  try {
    folder.mkdirs();
  } catch(Exception e) {
    JOptionPane.showMessageDialog(null, "There was an error: \n"+e, "Error!", 1);
  }
}

it creates a folder name “~” and a folder inside that named “test” in the directory my project is in.

How can i get Java to create the folder in my home folder?

Thanks!

You can get the user directory path by getting the system property “user.home”

System.getProperty("user.home");
