Chapter 9, Problem 4FTE

Explanation of Solution

Given statements:

//Tokenize a string that is delimited

//with semicolons. The string has 3 tokens

String str = "one;two;three"; //Line 1

String tokens = str.split(";"); //Line 2

System.out.println(tokens); //Line 3

Error in the given statement:

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.

Error #1:

The “tokens” variable must reference the array of tokens that is returned by the method “split ()” in “Line 2”. So the statement must be rewritten as:

String[] tokens = str...
