Learning content summary
Initial understanding of java programming, c language programming and feel there are some similarities. But for Java object-say this is still not quite understand. For identifiers reserved words, names, comments, etc. grasp okay, the program development process is still not clear.
Textbook learning and problem-solving process
Question 1: For Java object-say not quite understand this
Problem 1 Solution: own the Internet Baidu, access to textbooks in class listening to the teacher, to practice, ask Alumni Association, should be resolved later.
Question 2: textbooks mentioned object should be packaged, the object should be a self-managing. That in the end what is object-oriented, what is process-oriented
Problem 2 Solution: Check the website
What is object-oriented and process-oriented.
Code debugging and problem solving in the process

Problem 1 Solution: Open the file folder and then debugging, example "/ bin" within the meaning of the bin folder, to establish their own should find the location of the file created.
