How to create a temporary directory/folder in Java?

To create a temporary directory/folder in Java, you can use the createTempDirectory() method of the Files class in the java.nio.file package. This method creates a new directory in the default temporary-file directory and returns a Path object pointing to the new directory.

Here is an example of how to create a temporary directory in Java:

Path tempDir = Files.createTempDirectory("temp");
System.out.println(tempDir); // prints the path of the temporary directory

You can also specify a prefix and a suffix for the temporary directory by passing them as arguments to the createTempDirectory() method. For example:

Path tempDir = Files.createTempDirectory("prefix-", "-suffix");
System.out.println(tempDir); // prints the path of the temporary directory

The createTempDirectory() method throws an IOException if an I/O error occurs while creating the temporary directory.

I hope this helps. Let me know if you have any questions.
