  System.out.println("Complete sentence: \n"+sBuffer);
  
  //To know the length of StringBuffer
  System.out.println("Sentence length = "+sBuffer.length());
  
  //To get a character at a particular position
  System.out.println("Character at position 5 is :: "+sBuffer.charAt(5));
  
  //To get a part of string
  System.out.println(sBuffer.substring(21, 34));
  
  //To reverse StringBuffer
  System.out.println("Reverse  = "+sBuffer.reverse());
  
 }
}
