public class StringBufferDemo {

   public static void main(String[] args) {

      StringBuffer buff = new StringBuffer("TUTORIALS");
      System.out.println("buffer = " + buff);

      // returns the codepoint at index 5
      int retval = buff.codePointAt(5);
      System.out.println("Character(unicode point) = " + retval);
    
      buff = new StringBuffer("amrood admin ");
      System.out.println("buffer = " + buff);
  
      // returns the codepoint at index 6 i.e whitespace character
      retval = buff.codePointAt(6);
      System.out.println("Character(unicode point) = " + retval);
   }
}
