Usage

From source file:MainClass.java

public static void main(String[] arg) {
    String text = "To be or not to be";

    char[] textArray = new char[3];
    text.getChars(9, 12, textArray, 0);

    for (char ch : textArray) {
        System.out.println(ch);//from w  ww.  j  a v  a 2  s.  co m

    }
}

From source file:Main.java

public static void main(String args[]) throws IOException {
    String source = "test";

    FileWriter f0 = new FileWriter("file1.txt");
    for (int i = 0; i < buffer.length; i += 2) {
        f0.write(buffer[i]);//from   ww w  . ja v  a 2s  .  c  om
    }
    f0.close();

    FileWriter f1 = new FileWriter("file2.txt");
    f1.write(buffer);
    f1.close();

    f2.write(buffer, buffer.length - buffer.length / 4, buffer.length / 4);
    f2.close();
}
