Yes there is one,

In the class java.io.File you have the following methods:

static File createTempFile(String prefix, String suffix)

Creates an empty file in the default temporary-file directory, using the given prefix and suffix to generate its name.

static File createTempFile(String prefix, String suffix, File directory)

Creates a new empty file in the specified directory, using the given prefix and suffix strings to generate its name.

With them you can create a temporary file.

You then need to call the method deleteOnExit() on each temporary file if you want them to be deleted when you exit the program.

You can find more info in the doc of this class.
