Creating a char view of a ByteBuffer using asCharBuffer view

Demo Code

import java.nio.Buffer;
import java.nio.ByteBuffer;
import java.nio.ByteOrder;
import java.nio.CharBuffer;

public class Main {
  public static void main(String[] argv) throws Exception {
    ByteBuffer byteBuffer = ByteBuffer.allocate(7).order(ByteOrder.BIG_ENDIAN);
    CharBuffer charBuffer = byteBuffer.asCharBuffer();

    byteBuffer.put(0, (byte) 0);
    byteBuffer.put(1, (byte) 'H');
    byteBuffer.put(2, (byte) 0);
    byteBuffer.put(3, (byte) 'i');
    byteBuffer.put(4, (byte) 0);
    byteBuffer.put(5, (byte) '!');
    byteBuffer.put(6, (byte) 0);

    println(byteBuffer);/*w  ww.ja  v  a2 s. c o  m*/
    println(charBuffer);
  }

  // Print info about a buffer
  private static void println(Buffer buffer) {
    System.out.println("pos=" + buffer.position() + ", limit=" + buffer.limit()
        + ", capacity=" + buffer.capacity() + ": '" + buffer.toString() + "'");
  }
}
