Question
Chapter 8.4, Problem 8.19CP
Program Plan Intro
String class:
- The “String” class provides a number of methods that examines for a string inside of a string.
- The term “substring” refers to a string that denotes another string’s part.
- The “startsWith” method would determine whether calling string of object begins with a specific substring.
- The method returns “true” if string begins with specified substring, it returns “false” otherwise.
- The “endsWith” method would determine whether calling string would end with a specified substring.
- The method returns “true” if string ends with specified substring, it returns “false” otherwise.
- The “regionMatches” method would determine whether specified regions for two strings match.
- The first argument of this method can be “true” or “false” that indicates whether a case-insensitive comparison could be performed.
StringBuilder class:
- The “StringBuilder” class is same as “String” class except that contents of “StringBuilder” objects could be changed.
- It provides several methods that “String” class does not have.
- The “append” method accepts an argument that might be a primitive data type.
- It appends a string representation to contents of calling object.
- The “insert” method accepts two arguments, an integer that specifies position in string of calling object as well as value to be inserted.
- The “replace” method replaces the occurrences of one character with another character.
- The “toString” method converts a “StringBuilder” object in to a regular string.
Given code:
String city = “Asheville”;
Explanation:
The given code stores a string value to a variable that denotes a “String” object.

Students have asked these similar questions
StringBuilder objects should be used in place of String objects if
O is more than 80 characters long.
the string may grow.
O the string is declared final.
O the tring needs to be initialized.
3. Complete the implementations of the conversion methods:
a. double toDouble () const;
This method returns the corresponding value the string in double type. For example, if we
have an object str: CustomString str("99.50");
then this operation: double number
will give the number = 99.50.
= str.toDouble();
In the class String, the substring method inserts a String into another String.
-True
or
-False

The method should accept two arguments: a reference toa String object and an integer. The integer argument is a character position within theString, with the first character being at position 0.

The method does not return anything.Here is an example of a call to the method:showChar("New York", 2);In this call, the method will display the character w because it is in position 2.

Because ticket agents frequently mistype long ticket numbers, Travel Tickets has asked you to write an application that indicates invalid ticket number entries. The class prompts a ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you drop the last digit of the number, then divide the number by 7, the remainder of the division will be identical to the last dropped digit. Accept the ticket number from the agent and verify whether it is a valid number. Test the application with the following ticket numbers: . 123454; the comparison should evaluate to true . 147103; the comparison should evaluate to true . 154123; the comparison should evaluate to false Save the program as TicketNumber.java.arrow_forward
