Usage

From source file:MainWindowLogic.java

static void isTextFile(File fil_hnd) throws IncorrectFileTypeException, FileNotFoundException, IOException {
    FileInputStream in = new FileInputStream(fil_hnd);
    int size = in.available();
    if (size > 1000)
        size = 1000;//  ww  w  .jav a2 s . c o m
    byte[] data = new byte[size];
    in.read(data);
    in.close();
    String s = new String(data, "ISO-8859-1");
    String s2 = s.replaceAll("[a-zA-Z0-9\\.\\*!\"\\$\\%&/()=\\?@~'#:,;\\"
            + "+><\\|\\[\\]\\{\\}\\^\\\\ \\n\\r\\t_\\-`"
            + "??]", "");
    // will delete all text signs

    double d = (double) (s.length() - s2.length()) / (double) (s.length());
    // percentage of text signs in the text
    if (!(d > 0.950))
        throw new IncorrectFileTypeException();
