201671010135 2016--2017--Java Programming: Seventh chapter exceptions, assertions and logs

Finished the four, five, six chapters of the content, we this week's Java learning into the anomaly, assertions and logs, remember that the teacher said that three chapters is the core of Java, is the core will be more difficult, anyway, I learned when the confused. After I learned the anomaly, the assertion and the log, I regained confidence in Java.

This week's learning content is not very difficult, coupled with the teacher explained in detail again, I have the exception and assertion of the grammar point basically mastered, some relatively simple program I can add exceptions or assertion processing code, but in the experimental report to some more complex program add exception and assertion processing code, I was a little confused , do not know what to add the exception class, do not know where to add the exception code, but I think this should also be normal, because the initial stage of learning, we are not very familiar with the Java framework, with the increase of knowledge, I will slowly understand and apply to him skillfully.

Log that a teacher let us teach ourselves, I read it myself, probably understand his grammar point, by writing that a book on the program, I see that is about the GUI code, the original Java also has about the GUI syntax point, this and Python is similar point.

Overall, this week's Java learning I have a great harvest, the remaining problems I will be through their own efforts to solve.
