Files - operations on file content. StandardCharsets and Charset (an older class), for encodings of text files. the File.toPath method, which lets older code interact nicely with the newer java.nio API. In addition, the following classes are also commonly used with text files, for both JDK 7 and earlier versions: Scanner - allows reading files in a compact wayBufferedReader - readLineBufferedWriter - write + newLine When reading and writing text files: it's often a good idea to use buffering (default size is 8K)there's always a need to pay attention to exceptions (in particular, IOException and FileNotFoundException)
