Kirkland Grace Hospital loves the new Limit feature but now they are looking for a couple of enhancements:

1. If the temperature is right around the limit boundary, the caregivers can get peppered by messages if the temperature goes back and forth outside and within the limit. They are looking for a way to minimize this chatter. An example might be when the temperature is going back and forth between 37.6 and 37.7. Each transition would create a new message.

1. KGH would like the option to be able to change some of the text in the messages. Specifically, they would like to have an option to change the text that describes the high, low, and return states. "Over High", "Under Low", and "In Range" are good defaults but KGH would like to be able to try different phrases.

Again, MedCo's programmers get together and decide this can be done with Java by editing the class called Limit:

• New variables to hold the strings to display for High, Low, and Return conditions.
• Setter methods to set each new variable individually and a 4^th Setter method to update all three in one call.
• A new feature called a deadband. The deadband will be a new variable that will default to 0.1. There will be Getter and Setter methods for the deadband. The check for return to normal will now be:
  • If previous state was HIGH, if value <= high - deadband then normal.
  • If previous state was LOW, if value >= low + deadband then normal.

Submission:

Submit both your source file (Limit.java) with code for all of the Methods discussed above and the Methods from Stage I. Also submit the Test Code - preferably in a separate .java file. If you are using the simulated clock from last week and you have it in a separate file, then submit that file also.

Here is the code from stage 1. If you could include comments so that I understand the code that would be really helpful. Thank you.
