title: Java class Circuit for a light switch
body: <p>I am not sure how to even start this simple program. I am over thinking this and I haven't really learned how to do something like this. This is the description:</p>
  
  <p>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 light on or off. I have these methods but unsure about how to use them. </p>
  
  <pre><code>public int getFirstSwitchState() (0 for down "off", 1 for up "on")
  
  public int getSecondSwitchState() (0 for down "off", 1 for up "on")
  
  public int getLightState() (0 for "off", 1 for "on")
  
  public void toggleFirstSwitch()
  
  public void toggleSecondSwitch()
  
  public int getSwitchState(int switch)
  
  public void toggleSwitch(int switch)
  </code></pre>
  
  <p>Then have a TestCircuit class that tests all switch combinations, printing out actual and expected states for the switches and light </p>
