java class work of students

Topic, write a Java application. Design a student class Students, including attributes are: serial number, student number, name, sex, profession, three courses scores (math, computer, English); methods include: seeking total score, average score, in addition to the serial number of each attribute assignment method, each attribute value of the acquisition method and so on. Description: Creates a Per Students object, the sequence number value by 1 ; the first sequence number value of a student object 1 .

Write a main class StudentsDemo, creating class Students five objects in the main process, the output information according to the following requirements:

(1) Each curriculum highest / lowest score students serial number, student number, course name and the score

(2) Total maximum / minimum number of students, number, name and score all courses

(3) Enter a number or school name, if there is such a student number or the names of all the student information is output, otherwise the output information does not exist.
