Writes chars of the given string to the current position of this buffer, and increases the position by the number of chars written.

Usage

From source file:Main.java

public static void main(String[] args) {
    CharBuffer cb1 = CharBuffer.allocate(5);
    cb1.put("java2s.com", 0, 2);
    cb1.rewind();//from  w w  w.j a  v  a  2  s  .  c o m

    System.out.println(cb1.toString());
}

    CharBuffer cb = CharBuffer.allocate(length);
    cb.put(buffer, offset, length);
    cb.flip();/*ww  w  .j a  v  a2s  .c o m*/

    return Charset.defaultCharset().encode(cb).array();
