Use a Scanner:

Scanner file = new Scanner(new File("test.txt"));

String contents = file.nextLine();

file.close();

Of course, if your file has multiple lines you can call nextLine multiple times.

BufferedReader br = new BufferedReader(new FileReader("file.txt"));

try {
    StringBuilder sb = new StringBuilder();
    String line = br.readLine();

    while (line != null) {
        sb.append(line);
        sb.append("\n");
        line = br.readLine();
    }
    String everything = sb.toString();
} finally {
    br.close();
}
