定义学生类student有三个属性成绩

Ⅰ 求一道编程题。我创建了学生类。定义了3个字段。名称，成绩。和总成绩。但是编写的求和方法为什么只能。

Sum函数不要这样写嘛，给它传个参数，传1就计算第1次的返回，传2就计算第2次的返回

Ⅱ 定义一个学生类,有姓名,学号,成绩(int类型)三个属性 求大神帮助啊！谢谢各位

importjava.util.ArrayList;
importjava.util.Collections;
importjava.util.List;

publicclassSorter{

	publicstaticvoidmain(String[]args){

		<Student>students=newArrayList<Student>();
		
		Studentstudent1=newStudent();
		student1.id="1";
		student1.name="张三";
		student1.score=60;
		students.add(student1);
		
		Studentstudent2=newStudent();
		student2.id="2";
		student2.name="李四";
		student2.score=70;
		students.add(student2);
		
		Studentstudent3=newStudent();
		student3.id="3";
		student3.name="王二";
		student3.score=80;
		students.add(student3);
		
		Collections.sort(students);
		
		for(Studentstudent:students){
			System.out.println("编号："+student.id+",姓名："+student.name+",成绩："+student.score);
		}
		
	}
	
}

<Student>{
	
	publicStringid;
	publicStringname;
	publicintscore;
	
	@Override
	publicintcompareTo(Studento){
		if(score>o.score){
			return-1;
		}elseif(score<o.score){
			return1;
		}
		return0;
	}
	
}

Ⅲ 定义一个学生类，包含学号、姓名和总分三个属性，要求创建5个学生对象，并查找总分大于200分学生的信息

import java.util.Scanner;

class Students{
protected int sid; //学号
protected String name; //姓名
protected double score; //总分

public Students(){
}

public Students(int sid, String name, double score){
this.sid = sid;
this.name = name;
this.score = score;
}

public double getScore(){
return this.score;
}

public void display(){
System.out.println("学号：" + sid);
System.out.println("姓名：" + name);
System.out.println("总分：" + score);
}
}
public class Test26 {
public static void main(String[] args) {
Students[] studs = new Students[5];
int i;
int sid;
String name;
double score;
Scanner scan = new Scanner(System.in);

System.out.println("添加学生信息");
for(i=0; i<studs.length; i++){
System.out.print("学号：");
sid = scan.nextInt();
System.out.print("姓名：");
name = scan.next();
System.out.print("总分：");
score = scan.nextDouble();
studs[i] = new Students(sid, name, score);
}

System.out.println("总分大于200分学生的信息");
for(i=0; i<studs.length; i++){
if(studs[i].getScore() > 200){
studs[i].display();
}
}
}
}

Ⅳ 定义一个学生类, 需要有姓名, 年龄, 考试成绩三个成员属性. 属性(成员变量)需要私有并提供get, set方法.

public class Student {

内private String name ;
private int age;
private double Exam;
public String getName() {
容return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public double getExam() {
return Exam;
}
public void setExam(double exam) {
Exam = exam;
}

}

Ⅳ java:定义学生类Student, 其中属性有 name， id， score ,分别表示姓名，学好，成绩.....

定义一个表示学生信息的类Student，要求如下：

（1）类Student的成员变量：

sNO表示学号；sName表示姓名；sSex表示性别；表示年龄；sJava：表示Java课程成绩。

（2）类Student带参数的构造方法：

在构造方法中通过形参完成对成员变量的赋值操作。

（3）类Student的方法成员：

getNo（）：获得学号；

getName（）：获得姓名；

getSex（）：获得性别；

getAge（）获得年龄；

getJava（）：获得Java课程成绩

（4）根据类Student的定义，创建五个该类的对象，输出每个学生的信息，计算并输出这五个学生Java语言成绩的平均值，以及计算并输出他们Java语言成绩的最大值和最小值。*/

  测试代码

Student *stu=[Student new];
[stu setScore:65.5];
[stu setAge:21];
[stu setName:@"zhangsan"];
Student *stu1=[Student new];
[stu1 setScore:70.3];
[stu1 setAge:19];
[stu1 setName:@"lisi"];
Student *stu2=[Student new];
[stu2 setScore:56.5];
[stu2 setAge:18];
[stu2 setName:@"wangwu"];
Student *stu3=[Student new];
[stu3 setScore:85.6];
[stu3 setAge:25];
[stu3 setName:@"mingming"];
Student *stu4=[Student new];
[stu4 setScore:95.4];
[stu4 setAge:20];
[stu4 setName:@"xionghong"];
NSArray *stuArr=[NSArray arrayWithObjects:stu,stu1,stu2,stu3,stu4, nil];
NSArray *sortArr=[stuArr sortedArrayUsingSelector:@selector(compareWithScore:)];
NSLog(@"按成绩排序后：");
for (int i=0; i<sortArr.count; i++) {
Student *a=[sortArr objectAtIndex:i];
NSLog(@"Myname is %@,age is %d,score is %f",a.name,a.age,a.score);
}
NSArray *sortArr1=[stuArr sortedArrayUsingSelector:@selector(compareWithAge:)];
NSLog(@"按年龄排序后：");{
for (int i=0; i<sortArr1.count; i++) {
Student *a=[sortArr1 objectAtIndex:i];
NSLog(@"Myname is %@,age is %d,score is %f",a.name,a.age,a.score);
}
}
NSArray *sortArr2=[stuArr sortedArrayUsingSelector:@selector(compareWithName:)];
NSLog(@"按姓名排序后：");{
for (int i=0; i<sortArr2.count; i++) {
Student *a=[sortArr2 objectAtIndex:i];
NSLog(@"Myname is %@,age is %d,score is %f",a.name,a.age,a.score);
}
}

Ⅶ 定义一个学生类，需要有姓名，年龄，考试成绩三个成员属性，创建5个对象，属性可以任意值。（Objective-C

1. 创建一个Obj,设置obj的三个属性（string类型）：姓名、年龄、成绩；

2. 给obj每个属性赋值的时候，重写每个属性的set、get、方法；

3. 赋值完成后，存入数组；

4. 查询的时候写个排序算法，输出打印

Ⅷ 【java】定义学生类,包含三个属性:学号,成绩,及入学日期(日期也为类【急求！！】

最简单的就是重写学生类的 equals() 和 hashCode() 以 入学日期为关键字段, 然后调用Arrays.sort() 方法, 默认就是升序排序

Ⅸ 定义一个学生类, 需要有姓名, 年龄, 考试成绩三个成员属性

public class Student {
private String name;private int age;private double score;public Student(String name,int age,double score){
this.name=name;
this.age=age;
this.score=score;
}
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 double getScore() {
return score;
}
public void setScore(double score) {
this.score = score;
}

Ⅹ 定义一个表示学生的类(Student) Student类包括表示学生的学号姓名性别年龄和3门课程成绩的信息数据及

这是学生类:
public class Student {

private int xuehao;

private String xingming;

private String xingbie;

private int shuxue;

private int yuwen;

private int yingyu;

public int getShuxue() {
return shuxue;
}

public void setShuxue(int shuxue) {
this.shuxue = shuxue;
}

public String getXingbie() {
return xingbie;
}

public void setXingbie(String xingbie) {
this.xingbie = xingbie;
}

public String getXingming() {
return xingming;
}

public void setXingming(String xingming) {
this.xingming = xingming;
}

public int getXuehao() {
return xuehao;
}

public void setXuehao(int xuehao) {
this.xuehao = xuehao;
}

public int getYingyu() {
return yingyu;
}

public void setYingyu(int yingyu) {
this.yingyu = yingyu;
}

public int getYuwen() {
return yuwen;
}

public void setYuwen(int yuwen) {
this.yuwen = yuwen;
}

public int average(int x,int y,int z){

return (x+y+z)/3;

}

}

这是测试类:
public class TestStudent{
public static void main(String args[]) {
Student st1=new Student();
st1.setShuxue(75);
st1.setYingyu(80);
st1.setYuwen(85);
System.out.println("第一个学生的平均成绩为:"+st1.average(st1.getShuxue(),st1.getYingyu(),st1.getYuwen()));
Student st2=new Student();
Student st3=new Student();
Student st4=new Student();
Student st5=new Student();

}

}
你要求5个学生对象,我写出一个,后面的依次类推.应该会吧.
