TAILIEUCHUNG - Lecture Object Oriented Programing - Chapter 30: Strings, characters and regular expressions

In this chapter you will learn: To create and manipulate immutable character string objects of class String, to create and manipulates mutable character string objects of class StringBuilder, to create and manipulate objects of class character, to use a StringTokenizer object to break a String object into tokens, to use regular expressions to validate string data entered into an application. | 30 Strings, Characters and Regular Expressions The chief defect of Henry King Was chewing little bits of string. —Hilaire Belloc Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences. —William Strunk, Jr. I have made this letter longer than usual, because I lack the time to make it short. —Blaise Pascal OBJECTIVES In this chapter you will learn: To create and manipulate immutable character string objects of class String. To create and manipulates mutable character string objects of class StringBuilder. To create and manipulate objects of class Character. To use a StringTokenizer object to break a String object into tokens. To use regular expressions to validate String data entered into an application.
