Completed the first test before Java class this week the main volume of work, did a student information management systems. Or with a lot of harvest, the recent study of Java knowledge to use. But the feeling is still thinking in C
++ do thinking student information management system, but there is a part of the changes, such as the focus on the application in C ++ pointers, but in java but never felt a pointer, Java pointer buried very deep, because most instances pointer java into an object. So learners feel the existence of the pointer.
By doing this student information management system, I learned to use an array of java, there's also Java input and output, as well as toString (); middle encountered a lot of problems. For example, when the input easy error, because the input string and integer input there is a conflict, so in order to declare Scanner class in various methods. There has deepened, additions and deletions to change search the basic idea, to do this procedure in the process, they learn to feel more convenient to use an array collection ratio.
