Java Files.exists() is a method in Java's java.nio.file.Files class that checks if a file or directory exists at the specified path. It returns true if the file or directory exists, and false if it does not. Introduced in Java 2007 with Java 7, exists() is useful for verifying the presence of a file before performing file operations like reading or writing.
