Alternatively, you can use `createTempFile` from from [`java.io.File`](https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/io/File.html#createTempFile(java.lang.String,java.lang.String)) or [`java.nio.Files`](https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/nio/file/Files.html#createTempFile(java.lang.String,java.lang.String,java.nio.file.attribute.FileAttribute...)) to create a file in the temp directory, its parent is the path to the temp directory.
