Answer» 1. Design a class to represent a geometric rectangle with a given length and width, such that it is capable of calculating the AREA and the perimeter of the rectangle. 2. Define a class that represents a TEMPERATURE object. It should store the CURRENT temperature in an instance variable of type double, and it should have two public methods, setTemp(double t), which assigns t to the instance variable, and getTemp(), which returns the value of the instance variable. 3. Define a class named TaxWhiz that computes the sales TAX for a purchase. It should store the current tax RATE as an instance variable. You can initialize the rate using a TaxWhiz() method. This class should have one public method, calcTax(double purchase), which returns a double, whose value is purchases times the tax rate. For example, if the tax rate is 4 percent, 0.04, and the purchase is $100, the calcTax() should return 4.0 Many thanks to all of you. Figure 1.8.Sorry, we don't do homework.
