Method

voidprint(ByteBuffer bb)
print 
System.out.println("position =" + bb.position() + ", rmaining=" + bb.remaining() + ", limit=" + bb.limit());
Stringprint(ByteBuffer byteBuffer)
print 
String text = new String(byteBuffer.array());
return print(text);
voidprintBuffer(ByteBuffer buffer)
print Buffer 
byte[] bytes = new byte[buffer.remaining()];
buffer.get(bytes);
System.out.println(Arrays.toString(bytes));
voidprintBuffer(ByteBuffer buffer)
Prints the given buffer in hex format from the 0 position to the limit. 
for (int i = 0; i < buffer.limit(); i++) {
    System.out.format("%x ", buffer.get(i));
StringprintBuffer(String msg, ByteBuffer buffer)
Print the contents of the buffer out to the PrintStream in hex and ASCII. 
StringBuffer sbuf = new StringBuffer();
int length = buffer.position();
sbuf.append("--------------------------------------------------------\n\n");
sbuf.append(msg).append("\n");
sbuf.append("\n");
sbuf.append("Thread  : ").append(Thread.currentThread().getName()).append("\n");
sbuf.append("Total length (ByteBuffer position) : ").append(length).append("\n");
sbuf.append("Byte Buffer capacity               : ").append(buffer.capacity()).append("\n\n");
...
StringprintByteBuffer(ByteBuffer buf)
print Byte Buffer 
StringWriter w = new StringWriter();
byte[] data = bbToArray(buf);
w.append('[');
w.append(formatHex(data));
if (data.length == 4) {
    w.append(" int:");

voidprintImageContentsSubset(ByteBuffer buf, int w, int h)
Print a small subset of the given image, namely the upper left 20x20. 
int lineSize = w * 4;
w = (w > 20) ? 20 : w;
h = (h > 20) ? 20 : h;
IntBuffer ibuf = buf.asIntBuffer();
int nextLine = 0;
for (int y = 0; y < h; y++, nextLine += lineSize) {
    ibuf.position(nextLine);
    for (int x = 0; x < w; x++) {
...
voidprintln(String string, ByteBuffer buffer)
println 
if (buffer == null || !buffer.hasRemaining())
    return;
byte[] bytes = new byte[buffer.remaining()];
buffer.get(bytes);
buffer.flip();
println(string, bytes);
