This question is based on the class diagram shown in Figure 1. The parent class contains the general information about transaction and an abstract method to calculate the bonus. For purchase, the bonus calculation is amount * 0.5 and for sale the bonus calculation is amount * 0.2. All the data members of the Transaction class are initialized through a constructor with parameter set. Write the full Java class code for the Transaction class that has a show amount method. Then, write the class code for subclasses for Purchase and Sale that will implement the interest calculation methods. Transaction Purchase Sale Figure 1
