Question 1:

1) Design a class named StockTransaction that holds a stock symbol (typically one to four characters), stock name, and price per share. Include methods to set and get the values for each data field. Create the class diagram and write the pseudocode that defines the class.

2) Design an application that declares two StockTransaction objects and sets and displays their values.

3} Design an application that declares an array of 10 StockTransactionobjects. Prompt the user for data for each object, and then display all the values.

4) Design an application that declares an array of 10 StockTransactionobjects. Prompt the user for data for each object, and then pass the array to a method that determines and displays the two stocks with the highest and lowest price per share.

Question 2:

1) Design a class named PhoneCall with four fields: two strings that hold the 10-digit phone numbers that originated and received the call, and two numeric fields that hold the length of the call in minutes and the cost of the call. Include a constructor that sets the phone numbers to Xs and the numeric fields to 0. Include get and set methods for the phone number and call length fields, but do not include a set method for the cost field. When the call length is set, calculate the cost of the call at three cents per minute for the first 10 minutes, and two cents per subsequent minute. Create the class diagram and write the pseudocode that defines the class.

2) Design an application that declares three PhoneCalls. Set the length of one PhoneCall to 10 minutes, another to 11 minutes, and allow the third object to use the default value supplied by the constructor. Then, display each PhoneCall's values.

3) Create a child class named InternationalPhoneCall that inherits from PhoneCall. Override the parent class method that sets the call length to calculate the cost of the call at 40 cents per minute.

4) Create the logic for an application that instantiates a PhoneCall object and an InternationalPhoneCall object and display the costs for each.
