3. (15 points) a. Write an if/else statement that assigns true to the variable fever if the variable temperature is greater than 98.6; otherwise it assigns false to fever. b. On what values of temperature would you test your code in part a, in order to test each path and boundary as we discussed in class (Oust with respect to the code in part a) ? 4.

In the code appropriately, in order to extract the first and last initials from fulName. the String class. Here is the This requires calling methods which are already defined in ocumentation that the Java Standard Library provides for relevant String methods. You need not invoke all of these methods.
