Assume the existence of the following Java GUI application. There are two text fields for user input. The first JTextField variable is named voltage and is used to input a voltage value in volts. The second JTextField variable named resistance is used to input a resistance value in ohms. All input values and calculations use floating point values. The user clicks a JButton to perform a calculation. One JButton called current causes the program to calculate and display the current flowing through the resistor, I = V / R. Another JButton called power causes the program to calculate the power being dissipated by the resistor, P = V * V / R. The result of the selected calculation is displayed in an output text area variable named output. The output string should say something like this: "10 volts dropped across 1000 ohms creates 0.1 amps." Clicking one of the buttons generates the event which causes the program to do the selected calculation and update the output area. Assume the user interface has already been implemented and the member variables listed above exist. Your job is to write the ButtonHandler inner class which handles the events from the two buttons, does the requested calculation and displays the appropriate result.
