About class member access illustrated in fig08_03: o Test this example code and explain why the program cannot get o Make necessary changes on the test class MemberAccessTest to i.e., initialize the Timel object time with the same provided value the hour-minute-second values through the object time. o Take a screenshot of your updated code segment in the test class (not the output of the execution). o You may no do any changes on the class Timel.
// Fig. 8.3: MemberAccessTest.java
