Java Files.createTempFile() is a method in Java's java.nio.file.Files class that creates a new temporary file in the specified directory or the system's default temporary directory. It is commonly used in scenarios requiring temporary storage of data, such as testing, caching, or intermediate file handling. Introduced in Java 2007 with Java 7, createTempFile() is a convenient way to handle temporary files securely.
