Chapter 9, Problem 2SA

Explanation of Solution

Tokenizing string:

• It is a process of breaking down the string into the components called tokens.
• The string can be split using the split method which breaks the string using the delimiter for breaking it.
• The split method is used for the tokenizing the string.

Reason for tokenizing the string:

• It is a good idea to tokenizing the string because the programmer can use only the characters and not the whitespaces. Programmers can use the whitespaces as delimiters.
  • If the user gives leading whitespaces, then it will become the part of the 1^st token.
  • Similarly, if the user enters trailing whitespaces, then it will become part of the last token.

Example program:

//Declare the main class

public class Sample

{

//Declare the main method

public static void main(String args[])

{

String line = "cookies>milk>fudge:cake:ice cream";

//Create a array and store the strings

String[] token = line...
