Source Link

Document

Sets this scanner's delimiting pattern to a pattern constructed from the specified String .

Usage

From source file:MainClass.java

public static void main(String args[]) throws IOException {

    FileWriter fout = new FileWriter("test.txt");
    fout.write("2, 3.4,    5,6, 7.4, 9.1, 10.5, done");
    fout.close();//from   w ww . j a v a 2s .co  m

    FileReader fin = new FileReader("Test.txt");
    Scanner src = new Scanner(fin);
    // Set delimiters to space and comma.
    // ", *" tells Scanner to match a comma and zero or more spaces as
    // delimiters.

    src.useDelimiter(", *");

    // Read and sum numbers.
    while (src.hasNext()) {
        if (src.hasNextDouble()) {
            System.out.println(src.nextDouble());
        } else {
            break;
        }
    }
    fin.close();
