Get a substring

import java.nio.ByteBuffer;
import java.nio.CharBuffer;

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

    CharBuffer cbuf = buf.asCharBuffer();

    cbuf.put("a string");

    int start = 2; // start is relative to cbuf's current position
    int end = 5;
    CharSequence sub = cbuf.subSequence(start, end); // str
