打印信息表

假设一个年级有40名学生，他们的学号分别从128480到1244840，他们全部人都参加学校的化学，历史，地理，物理测试。下面将他们的全部成绩通过随机生成的方法进行打印出来，同时还要按顺序从大到小的排序出来。
具体的制作方法，要调用到多方面的元素来运行。如下图所示：
public class Fill {
public static void main(String[] args) throws IOException {
//实例化列表
List list = new ArrayList<>();
//实例随机的参数值
Random random = new Random();
for (int i = 1; i < 41; i++) {
//定义两个接受参数传过来的数值
String str="";
String str2="";
if (i<10) {
str=“128480”+i;
str2=“同学0”+i;
}else{
str=“12848”+i;
str2=“同学”+i;
}
//定义随机生成的成绩
int run1 = random.nextInt(100);
int run2 = random.nextInt(100);
int run3 = random.nextInt(100);
int run4 = random.nextInt(100);
//总成绩扽与其他成绩加起来的总数
int run5 = run1+run2+run3+run4;
//用If…else来对循环进行条件判断
if (run1>50) {
if (run2>50) {
if(run3>50){
if(run4>50){
list.add(new Pig(str,str2, run1, run2, run3, run4,run5));
}else{
//循环完之后对参数进行-参数值
i=i-1;
}
}else{
i=i-1;
}
}else{
i=i-1;
}
} else{
i=i-1;
}
}
//调用实例化的表格数据
Collections.sort(list);
//利用迭代器输出结果
Iterator it= list.iterator();
//while循环输出
while (it.hasNext()) {
Pig pig = (Pig) it.next();
System.out.println(“学校号：” + pig.getStudentNamber()+“学生名称：” + pig.getStudentName() + “历史分数：” + pig.getHistory() + “化学分数：”
+ pig.getGeography() + “地理分数：” + pig.getChemistry() + “物理分数：” + pig.getPhysics()+ “总分数：” + pig.getCount());
}
}
}
以下是定义整个程序的开发要点内容：（同时也是必须要定义的属性）
//申明一个类来传参数
class Pig implements Comparable{
private String StudentNamber;//学生在校的编号
private String StudentName;//学生的姓名
//private String Student;
private int Chemistry;//化学
private int History;//历史
private int Geography;//地理
private int Physics;//物理
private int Count;//学科的总分
//拼接所有的值
public Pig(String studentNamber, String studentName, int chemistry,
int history, int geography, int physics, int count) {
super();//指向的是自己本身的值
StudentNamber = studentNamber;
StudentName = studentName;
Chemistry = chemistry;
History = history;
Geography = geography;
Physics = physics;
Count = count;
}
//定义所有的数值应用对象
public String getStudentNamber() {
return StudentNamber;
}
public void setStudentNamber(String studentNamber) {
StudentNamber = studentNamber;
}
public String getStudentName() {
return StudentName;
}
public void setStudentName(String studentName) {
StudentName = studentName;
}
public int getChemistry() {
return Chemistry;
}
public void setChemistry(int chemistry) {
Chemistry = chemistry;
}
public int getHistory() {
return History;
}
public void setHistory(int history) {
History = history;
}
public int getGeography() {
return Geography;
}
public void setGeography(int geography) {
Geography = geography;
}
public int getPhysics() {
return Physics;
}
public void setPhysics(int physics) {
Physics = physics;
}
public int getCount() {
return Count;
}
public void setCount(int count) {
Count = count;
}
//定义排序数值的方法
@Override
public int compareTo(Pig o) {
// TODO Auto-generated method stub
return o.getCount()-this.getCount();
}
}
