[JAVA] ByteBuffer to String

How to copy from ByteBuffer to String

1. Simple but not exactly right    

simply create string with byte array from ByteBuffer 

ByteBuffer buffer = ByteBuffer.allocate(1024);

buffer.put(“aabcde”.getBytes());


String s = new String(buffer.array(), "");
 //or
String s = new String(buffer.array(), "UTF-8");

System.out.println(s);

buffer.put(“aabcde”.getBytes());

byte[] bytes = new byte[buffer.position()];

buffer.flip();       

buffer.get(bytes);

String s = new String(bytes); // or new String(bytes, "UTF-8");


System.out.println(s);
