Define ScoreInformation classes, including seven private variables (stunumber, name, mathematicsscore, englishiscore, networkscore, databasescore, softwarescore).
Five students and then deposit information, reuse and switch statements if realization: entry test scores, student test scores modify, calculate student achievement Grade Point Average, quit school management system functions.
This little test I found myself a lot of shortcomings, many do not know the basic syntax of Java, later to find time to replenish themselves.
