JAVA编写学生类student题目
（1）
public static void main(String[] args){
int count = 0;
for(int i=0;i100;i++){
if(i%3==0){
count+=i;
}
}
System.out.print("100以内能被3整除的和为："+count);
}
（2）
public class Student {
private String name ;
private int computer_score;
private int English_score;
private int Maths_score;
public Student(String name,int computer_score,int English_score,int Maths_score){
this.name=name;
this.computer_score = computer_score;
this.English_score=English_score;
this.Maths_score = Maths_score;
}
public void setName(String name){
this.name=name;
}
public void setComputer_score(int computer_score){
this.computer_score=computer_score;
}
public void setEnglish_score(int English_score ){
this.English_score = English_score;
}
public void setMaths_score(int Maths_score ){

}
public int getTotalScore( ){

}
public void introduce ( ){
System.out.print("姓名："+this.name+",总成绩为："+getTotalScore());
}
}
class homework2{
public static void main(String[] args){
Student xiaozhang = new Student("小张",60,70,80);

}
要求编写一个java程序，输入学生信息，并能保存与显示学生信息。
import java.util.ArrayList;
import java.util.Scanner;import com.sun.org.apache.xpath.internal.Arg;
public class Student {
//两个私有属性
private int no ;
private String name ;
//默认构造函数
public Student(){}
//带参构造函数
public Student(int no,String name){
this.no=no;
this.name=name;
}
//添加学生信息
public void addStudentInfo(ArrayList list){
String flag1="yes";
do{
Student student=new Student();
Scanner in =new Scanner(System.in);
System.out.println("请输入学生学号：");
student.setNo(in.nextInt());
System.out.println("请输入学生姓名：");
student.setName(in.next());
list.add(student);
System.out.println("是否继续添加学生信息(yes/no)?");
flag1=in.next();
} while(flag1.equals("yes"));
}
//读取学生信息
public void showStudentInfo(ArrayListStudent list){
System.out.println(" 学生no： "+" 学生name: ");
for(Student student:list){
System.out.println(" "+student.getNo()+" "+student.getName());
}
}
public int getNo() {
return no;
}
public void setNo(int no) {
this.no = no;
}
public String getName() {
return name;
}
public void setName(String name) {

}
public static void main(String arg[]) {
ArrayListStudent studentList= new ArrayListStudent();
Student student= new Student();
Scanner inn= new Scanner(System.in);
while(true){
System.out.println("----------------- 欢迎使用学生管理系统------------------");
System.out.println("1.输入学生信息");
System.out.println("2.显示学生信息");
System.out.println("0.退出系统");
System.out.println("请选择....");
int nn= inn.nextInt();
switch (nn) {
case 1:
student.addStudentInfo(studentList);
break;
case 2:
System.out.println("学生信息如下：");

break;
case 0:
System.exit(0);
System.out.println("系统退出！");
