201671010119 2016-2017-2 "Java program design" Nineth Week learning Experience

This week, through the experiment task one mastered the unchecked exception and checked exceptions, task three use of positive methods and negative methods of the last week's task of a procedure has been modified to make the procedure more perfect. Through other lab tasks, you learned about assertions and how to enable them in the compiler. The use and usage of the log system are understood by running the textbook program after class.

For task seven and task eight I don't know where to add the exception capture code. Task Nine does not define the two exception classes required by the teacher and does not know how to add the exception capture code. For exception capture, only the theoretical knowledge of it, for the application in the program is still very difficult, especially in a long program to add code. This aspect should also strengthen the practice, unifies the theory knowledge and the experiment.
