Write a Circuit Tester class that tests all switch combinations in Exercise •• E3.4, printing out actual and expected states for the switches and lamps.

Data from Exercise E3.4

Simulate a circuit for controlling a hallway light that has switches at both ends of
the hallway. Each switch can be up or down, and the light can be on or off. Toggling
either switch turns the lamp on or off.

Provide methods public int getFirstSwitchState() // 0 for down, 1 for up public int getSecondSwitchState() public int get LampState() // O for off, 1 for on public void toggleFirstSwitch() public void toggleSecondSwitch()
