How to convert ByteBuffer value into String

It depends what you have stored in the ByteBuffer (ints, doubles, chars, etc). You get() the data and print print it appropriatly.

e.g. the following puts a string a ByteBuffer then gets part of it back

// demo of byteBuffer
import java.nio.*;

class DemoByteBuffer{
  public static void main(String[] args){   
    String s="hello sam";
    System.out.println("s is " + s); 
    // convert String s to Bytes and warp in ByteBuffer buf
    ByteBuffer buf = ByteBuffer.wrap(s.getBytes());
    // convert another String to Bytes
    byte[] byte2 = (new String("hello tom").getBytes());
    System.out.println("byte2 is " + new String(byte2)); 
    // copy 3 bytes from buf position 6 to byte array position 6
    buf.position(6);
    buf.get(byte2, 6, 3);
    System.out.println("byte2 is " + new String(byte2)); 
  } 
}

when run gives
s is hello sam
byte2 is hello tom
byte2 is hello sam
