键盘录入5个学生信息并且存储到集合中(姓名,年龄，语文成绩,数学成绩,英语成绩), 按照总分从高到低输出到控制台 注：总分相同等情况下按照语文成绩排序，其次是数学成绩、英语成绩、年龄、姓名
1.先在main方法外定义一个学生类
class Student{
private String name;
private int age;
private int chinese;
private int math;
private int english;
public Student() {
}
public Student(String name, int age, int chinese, int math, int english) {
this.name = name;
this.age = age;
this.chinese = chinese;
this.math = math;
this.english = english;
}
//返回总成绩
public int getSum(){
return chinese + math + english;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public int getChinese() {
return chinese;
}
public void
