How to get file content in java?

Question

to get the content of a txt file I usually use a scanner and iterate over each line to get the content:

Scanner sc = new Scanner(new File("file.txt")); while(sc.hasNextLine()){     String str = sc.nextLine();                      } 

Does the java api provide a way to get the content with one line of code like:

String content = FileUtils.readFileToString(new File("file.txt")) 

Answer 1

Not the built-in API - but Guava does, amongst its other treasures. (It's a fabulous library.)

String content = Files.toString(new File("file.txt"), Charsets.UTF_8); 

There are similar methods for reading any Readable, or loading the entire contents of a binary file as a byte array, or reading a file into a list of strings, etc.

Note that this method is now deprecated. The new equivalent is:

String content = Files.asCharSource(new File("file.txt"), Charsets.UTF_8).read();
