java學生類

❶ java創建一個學生類

publicclassTest{

publicstaticvoidmain(String[]args){
ArrayList<Student>studentList=newArrayList<>();
studentList.add(newStudent("張三","class1","Java",85));
studentList.add(newStudent("周樂兒","class1","C#",79));
studentList.add(newStudent("王濤","class2","C#",52));
studentList.add(newStudent("李明","class2","Java",48));
//===========================================================================
System.out.println("姓名		班級名		課程名		考試成績");
for(Studentstudent:studentList){
System.out.println(student);
}
//===========================================================================
floatclass1SumScore=0;
intclass1StudentCount=0;
for(Studentstudent:studentList){
if(student.isClass1()){
class1SumScore+=student.getScore();
class1StudentCount++;
}
}
System.out.println("
class1班的總分："+class1SumScore+"	平均分："+class1SumScore/class1StudentCount);
//===========================================================================
floatjavaScore=0;
floatjavaStudentCount=0;
floatcSharpScore=0;
floatcSharpStudentCount=0;
for(Studentstudent:studentList){
if(student.isJava()){
javaScore+=student.getScore();
javaStudentCount++;
}elseif(student.isCSharp()){
cSharpScore+=student.getScore();
cSharpStudentCount++;
}
}
System.out.println("
Java課程的平均分："+javaScore/javaStudentCount+"	C#課程的平均分："+cSharpScore/cSharpStudentCount);
}
}

classStudent{
privateStringname;
privateStringclassName;
privateStringcourseName;
privateintscore;

publicStudent(Stringname,StringclassName,StringcourseName,intscore){
this.name=name;
this.className=className;
this.courseName=courseName;
this.score=score;
}

publicbooleanisClass1(){
return"class1".equals(className);
}

publicbooleanisJava(){
return"Java".equals(courseName);
}

publicbooleanisCSharp(){
return"C#".equals(courseName);
}

publicStringgetName(){
returnname;
}

publicStringgetClassName(){
returnclassName;
}

publicStringgetCourseName(){
returncourseName;
}

publicintgetScore(){

}

@Override
publicStringtoString(){
returnname+"		"+className+"		"+courseName+"		"+score;
}
}

❷ java編寫程序創建學生類

年齡、性別等 方法：愛好方法等等 2.創建2個學生子類

❸ JAVA創建一個學生類

public class Student {
private String id;
private String name;
private int age;
private String sex;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
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 String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
}
public class StudentToDo {
/**
* 吃飯方法
*/
public void eat(Student student){
System.out.println("id"+student.getId()+"年齡為"+student.getAge()+"性別是"+student.getSex()+"姓名叫"+student.getName()+"的學生在吃飯");
}
/**
* 打豆豆方法
*/
public void play(Student student){
System.out.println("id"+student.getId()+"年齡為"+student.getAge()+"性別是"+student.getSex()+"姓名叫"+student.getName()+"的學生在打豆豆");
}
}
public class Test {
public static void main(String[] args) {
StudentToDo studentToDo = new StudentToDo();
Student student = new Student();
student.setId("1");
student.setAge(15);
student.setName("張三");
student.setSex("男");
studentToDo.eat(student);
studentToDo.play(student);
}
}

❹ JAVA程序編寫一個學生類Student

Public Class Student{
Public long id;
Public String name;
Public int age;
Public boolean sex;
Public long phone;
Public Student(long i,String n,int a,boolean s,long p){
this.id = i;
this.name = n;
this.age = a;
this.sex = s;
this.phone = p;
}
Public int getage(){
return this.age;
}
Public long getphone(){
return this.phone;
}
Public String toString(){
return this.name;
}
Public static void main(String[]args){
Student student = new Student(01,"李明",20,true,13xxx);
System.out.println(student.age());
System.out.println(student.getphone());
System.out.println(student.toString());
}
}

}

❻ JAVA創建一個具體的學生類

//學生類
public class Student{
private String stu_id;
private String stu_name;
private float math;
private float chinese;
private float computer;

public void setStu_id(String stu_id){
this.stu_id=stu_id;
}
public String getStu_id(){
return stu_id;
}
public void setStu_name(String stu_name){
this.stu_name=stu_name;
}
public String getStu_name(){
return stu_name;
}
public void setMath(float math){
this.math=math;
}
public float getMath(){
return math;
}
public void setChinese(float chinese){
this.chinese=chinese;
}
public float getChinese(){
return chinese;
}
public void setComputer(float computer){
this.computer=computer;
}
public float getComputer(){
return computer;
}

}

//主方法的類
public class Start{
public static void main(String[] args){
Student stu1=new Student();
stu1.setStu_id("No1");
stu1.setStu_name("張三");
stu1.setMath(89.5f);
stu1.setChinese(70f);
stu1.setComputer(98f);
Student stu2=new Student();
stu2.setStu_id("No2");
stu2.setStu_name("李四");
stu2.setMath(79.5f);
stu2.setChinese(90f);
stu2.setComputer(68f);
float stu1Sum = stu1.getMath()+stu1.getChinese()+stu1.getComputer();
float stu2Sum = stu2.getMath()+stu2.getChinese()+stu2.getComputer();
if(stu1Sum > stu2Sum){
System.out.println ("總分最高分為："+stu1Sum);
System.out.println ("學號："+stu1.getStu_id());
System.out.println ("姓名："+stu1.getStu_name());
System.out.println ("數學："+stu1.getMath());
System.out.println ("語文："+stu1.getChinese());
System.out.println ("計算機："+stu1.getComputer());
}else if(stu1Sum < stu2Sum){
System.out.println ("總分最高分為："+stu2Sum);
System.out.println ("學號："+stu2.getStu_id());
System.out.println ("姓名："+stu2.getStu_name());
System.out.println ("數學："+stu2.getMath());
System.out.println ("語文："+stu2.getChinese());
System.out.println ("計算機："+stu2.getComputer());
}else{
System.out.println ("總分一樣高為："+stu1Sum);
System.out.println ("學號："+stu1.getStu_id());
System.out.println ("姓名："+stu1.getStu_name());
System.out.println ("數學："+stu1.getMath());
System.out.println ("語文："+stu1.getChinese());
System.out.println ("計算機："+stu1.getComputer());
System.out.println ("學號："+stu2.getStu_id());
System.out.println ("姓名："+stu2.getStu_name());
System.out.println ("數學："+stu2.getMath());
System.out.println ("語文："+stu2.getChinese());
System.out.println ("計算機："+stu2.getComputer());
}
}
}

希望對你有幫助!

❼ java作業求設計一個學生類

不難，就是費時間

❽ 在java中編寫程序，定義一個學生類

代碼如下：

package exam2;

import java.util.ArrayList;

import java.util.List;

/**

編寫一個Java應用程序，該程序包括3個類：

定義一個學生類，Student有姓名，學號，選學的課程列表

定義一個課程類：課程名稱，課程分數

(1)初始化一個學生，選擇了三門課程，並添加到學生的屬性中

(2)實現統計學生的總分功能

1.正確編寫2個類（5分）

2.統計學生的總分功能（5分）

*/

public class Test {

public static void main(String[] args) {

List<Course> courses = new ArrayList<>();

// 初始化3門課程及分數

Course course1 = new Course("java", 80);

Course course2 = new Course("Math", 60);

Course course3 = new Course("English", 90);

// 課程對象添加到集合

courses.add(course1);

courses.add(course2);

courses.add(course3);

// 初始化學生對象

Student student = new Student("tom", "2015101", courses);

// student.setStuid("2015101");

// student.setStuname("tom");

// student.setCourses(courses);

// System.out.println(student);

// (2)實現統計 學生 的總分功能

int sum = sumScore(courses);

System.out.println(student.getStuname() + "學生總分：" + sum);

}

private static int sumScore(List<Course> courses) {

int sum = 0;

// 用課程對象，來獲取課程的分數

for (Course course : courses) {

sum += course.getScore();

}

return sum;

}

}

package exam2;

import java.util.List;

public class Student {

// 定義一個學生類，Student有姓名，學號，選學的課程列表

private String stuname;

private String stuid;

private List<Course> courses;

public Student() {

}

public Student(String stuname, String stuid, List<Course> courses) {

this.stuname = stuname;

this.stuid = stuid;

this.courses = courses;

}

public String getStuname() {

return stuname;

}

public void setStuname(String stuname) {

this.stuname = stuname;

}

public String getStuid() {

return stuid;

}

public void setStuid(String stuid) {

this.stuid = stuid;

}

public List<Course> getCourses() {

return courses;

}

public void setCourses(List<Course> courses) {

this.courses = courses;

}

@Override

public String toString() {

return "學生姓名=" + stuname + ",學號=" + stuid + ", 課程=" + courses;

}

}

package exam2;

public class Course {

//定義一個課程類：課程名稱，課程分數

private String cname;

private int score;

public Course() {

}

public Course(String cname, int score) {

this.cname = cname;

this.score = score;

}

public String getCname() {

return cname;

}

public void setCname(String cname) {

this.cname = cname;

}

public int getScore() {

return score;

}

public void setScore(int score) {

this.score = score;

}

@Override

public String toString() {

return "[課程名稱=" + cname + ", 課程分數=" + score + "]";

}

}

/*

運行：

tom學生總分：230

*/

(8)java學生類擴展閱讀：

Public語句說明

1.Public語句聲明的變數在所有應用程序的所有沒有使用OptionPrivate Mole的模塊的任何過程中都是可用的；若該模塊使用了OptionPrivate Mole，則該變數只是在其所屬工程中是公用的。

2.使用Public語句可以聲明變數的數據類型。例如，下面的語句聲明了一個Integer類型的變數。

3.Public NumberOfEmployees As Integer 也可以使用Public語句來聲明變數的對象類型。下面的語句為工作表的新實例聲明了一個變數。
