Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    ByteBuffer buf = ByteBuffer.allocate(100);

    // Put values of different types
    buf.putChar((char) 123);

    // Reset position for reading
    buf.flip();/*from  w ww.  jav  a2s.  c  o m*/

    // Retrieve the values
    char c = buf.getChar();

}
