java作业

上海建桥学院实验报告课程名称： Java程序设计实验类型：设计型实验项目名称：类的设计与使用实验地点：计算中心326实验日期： 2018 年 5 月 24 日姓名：学号：班级：成绩：一、实验目的及要求培养面向对象的思想，要求能够用面向对象的思想去解决问题。

二、实验环境及要求jdk1.5以上的开发环境，可使用任何编辑器。

三、实验内容及步骤1.String name;String school’;String zy;String class;Double mxsj;Double wlsj;Double sore;已知学生类(Student)，该类中包含有如下成员变量和成员方法：1)成员变量年级、学院、专业、班级、姓名、面向对象程序设计、网络原理、数据库、总成绩Class student {}2)成员方法计算总成绩class Student {private String name;private double grade;public Student() {}public Student(String name, double grade) { = name;this.grade = grade;}public String getName() {return name;}public void setName(String name) { = name;}public double getGrade() {return grade;}public void setGrade(double grade) {this.grade = grade;}}public class txt1 {public static void main(String[] args) {Student stu1 = new Student();stu1.setName("zhangsan");stu1.setGrade(99);Student stu2 = new Student("lisi", 100);}} 2. (1)编写MyStudent类，通过该类在程序中直接为成员变量赋值，并通过控制台输出该生的姓名、学院、专业、班级和总成绩。

(2)通过构造函数为成员变量赋值，并通过控制台输出该生的姓名、学院、专业、班级和总成绩。

注意：要求以上的2种方法编程，输出结果相同四、源程序public class MyStudent {private String college;private String job;private String classes;private String name;private int oop;private int network;private int sql;private int sum;public MyStudent(String name,String college,String job, String classes, int oop, int network,int sql) { = name;this.college = college;this.job = job;this.classes = classes;this.oop = oop;work = network;this.sql = sql;}public int sum(){return oop+network+sql;}public String getCollege() {return college;}public void setCollege(String college) {this.college = college;}public String getJob() {return job;}public void setJob(String job) {this.job = job;}public String getClasses() {return classes;}public void setClasses(String classes) {this.classes = classes;}public String getName() {return name;}public void setName(String name) { = name;}public int getOop() {return oop;}public void setOop(int oop) {this.oop = oop;}public int getNetwork() {return network;}public void setNetwork(int network) {work = network;}public int getSql() {return sql;}public void setSql(int sql) {this.sql = sql;}public String toString() {return "姓名："+getName()+" "+"学院："+getCollege()+" "+"专业："+getJob()+" "+"班级："+getClasses()+" "+"总成绩："+sum();}public static void main(String[] args) {MyStudent test1=new MyStudent("cyb","外国语学院","计算机","计算机1班",89,86,99);}public int sum(){return oop+network+sql;}//getter,setter方法public String getGrade(){return grade;}public void setGrade(String grade){this.grade=grade;}public String getCollege(){return college;}public void setCollege(String college){this.college = college;}public void setJob(String job){this.job = job;}public String getClass(){return class;}public void setclass(String calss){this.class=class;}public String getName(){ = name;}public void setName(String name){=name}public int getOop(){return oop;}public void setOop(int oop){this.oop = oop;}public int getNetwork(){return network;}public void getNetwork(int network){work = network;}public int getSql(){return sql;}public void getSql(int sql){return sql = sql;}//to String 方法public String toString(){retunrn"年级："+getGrade()+""+"学院："+getCollege()+""+"专业："+getJob()+""+"班级："+getClass()+""+"姓名："+getName()+""+"面向对象程序设计："+getOop()+""+"网络原理："+""+getNetwork()+""+"数据库："+getSql()+""+"总成绩："+sum();}public static void main(String[]args){Student s = new Student();s.setGrade("大二")；s.setJob("计算机")；s.setClass("计算机一班")；s.setName("cyb")；s.setOop(89);s.setName(86);S.setSql(99);}}2.1).public class MyStudent {private String grade="大二";private String college="外国语学院";private String job="计算机";private String class="计算机1班";private String name="cyb";private int oop=89;private int network=86;private int sql=99;private int sum=oop+network+sql;public MyStudent(){}public String toString() {return "姓名："+name+" "+"学院："+college+" "+"专业："+job+" "+"班级："+class+" "+"总成绩："+sum;}public static void main(String[] args) {MyStudent ms=new MyStudent();}}五、实验结果六、分析与讨论（实验过程中发现的重点与难点，请认真总结）在一开始我认这门课光光是在于理论知识的，但是通过了这次的实验我理解到了，这是一门理论和实践相结合的，光光靠着理论知识是不能很好的来理解这门课的。
