Create the Control Panel interface that has the following 3 methods: public int warningLevel (); public String status (); public boolean isok (); Write 2 public static methods 1) Write a public static method that will take a single Control Panel parameter. The method must return whether or not a single parameter of type ControlPanel meets any of these criteria. critical if the ControlPanel: status equals "bad" or "emergency" or warningLevel is more than 10 or warningLevel is 7 or more and not Ok or warningLevel is less than 1 The ControlPanel parameter may be null, if so, system is not critical 2) Write a public static method called maxWarning() that will accept a List of Control Panel. The method must return the Control Panel that contains the maximum warningLevel. Important, if the List parameter is null OR if it contains no items, null must be returned. Hint, ControlPanel is an interface but that will not stop you from being able to code the problem. 380816.1612744.qx3zqy7 Current file: TestControl.java 1 //OPTIONAL 2 //Finish this class if you want to for testing.
