Chapter 1 Lab Alaorithme Frrors and Toetina napter 6 A First Look at Classes 11. Freezing and Boiling Points The following table lists rhe freezing and boiling points of several substances. Boiling Point Substance Freezing Point 172 Ethyl Alcohol -173 -306 -362 Oxygen 212 32 Water Design a class that stores a temperature in a temperature field and has the approne accessor and mutator methods for the field. In addition to appropriate constructors, the clas should have the following methods: isEthy1Freezing. This method should return the boolean value true if the tempern ture stored in the temperature field is at or below the freezing point of ethyl alcohol Otherwise, the method should return false. isEthy1Boiling. This method should return the boolean value true if the ture stored in the temperature field is at or above the boiling point of ethyl alcohol. Otherwise, the method should return false. isoxygenFreezing. This method should return the boolean value true if the tem- perature stored in the temperature field is at or below the freezing point of oxygen. Otherwise, the method should return false. isoxygenBoiling. This method should return the boolean value true if the tempera- ture stored in the temperature field is at or above the boiling point of oxygen. Oth- erwise, the method should return false. iswaterFreezing. This method should return the boolean value true if the tempera- ture stored in the temperature field is at or below the freezing point of water. Other wise, the method should return false. iswaterBoiling. This method should return the boolean value true if the tempera ture stored in the temperature field is at or above the boiling point of water. Other wise, the method should return false. Write a program that demonstrates the clas. The program should ask the user to enter temperature, and then display a list of the substances that will frecze at that temperature those that will boil at that temperature. For example, if the temperature is -20 the Cia report that water will freeze and oxygen will boil at that temperature. tempera- should 12. SavingsAccount Class Design a SavingsAccount class that stores a savings account's annual interest rate and bal ance. The class constructor should accept the amount of the savings account's starting bal- ance. The class should also have methods for subtracting the amount of a withdrawal, adding the amount of a deposit, and adding the amount of monthly interest to the balance. The monthly interest rate is the annual interest rate divided by twelve. To add the monthly inter est to the balance, multiply the monthly interest rate by the balance, and add the result ro the balance. Test the class in a program that calculates the balance of a savings account at the end of a period of time, It should ask the user for the annual interest rate, the starting balance, and
