怎样用JAVA设计学生类Student,包含“学号、班级、姓名、年龄、成员”

这个很简单呀，要自己试着去写。\r\npublic class Students {\r\n\tprivate String ID; //学号\r\n private String classId; //班级\r\n private String name; //姓名\r\n\tprivate int age; //年龄\r\n public Students(String ID,String classId,String name,int age){//构造函数\r\n this.ID=ID;\r\n this.classId=classId;\t\r\n this.name=name;\r\n this.age= age; \r\n }\r\n\tpublic String getiID() {//获得学号\r\n\t\treturn this.ID;\t\r\n }\r\n\tpublic String getClassId() {//获得班级\r\n\t\treturn this.classId;\r\n\t}\r\n\tpublic String getName() {//获得姓名\r\n\t\treturn this.name;\r\n\t}\r\n\tpublic int getAge() {//获得年龄\r\n\t\treturn this.age;\r\n\t}\r\n\t\r\n\tpublic void setAge(int age){//修改年龄\r\n\t\tthis.age=age;\r\n\t}\t\r\n\tpublic static void main(String args){\r\n\t\tStudents st=new Students("111101","一班","张三","20");\r\n\t\tSystem.out.println(st.getAge());\r\n\t\tst.setAge(30);\r\n\t\tSystem.out.println(st.getAge());\r\n\t}\r\n} \r\n如果在完整一些，可以在加一个toString（）函数，用来返回要输出的字符串。

Java：学生信息姓名、学号、成绩定义一个类，并定义相关的构造函数和方法来设置和获取相关的学生信息

1、代码如下：

Main类

import java.util.*;

import java.io.BufferedReader;

import java.io.InputStreamReader;

/**

 * Main 主方法

 * @author bufei

 * 

 */

public class Main {

    public static void main(String args) {

        stuGrad();

    }

    public static void stuGrad() {

        int stuNum = 1;

        Student;

        double;

        Map《Double, Integer》 map = new HashMap《》(stuNum);

        for (int i = 0; i 《 stuNum; i++) {

            System.out.println("请输入第 " + (i + 1) + " 个学生信息:");

            try {

                BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));

                System.out.println("姓名：");

                String name = reader.readLine();

                System.out.println("学号：");

                int id = Integer.parseInt(reader.readLine());

                System.out.print("语文：");

                double literature = Double.parseDouble(reader.readLine());

                System.out.print("数学：");

                double math = Double.parseDouble(reader.readLine());

                System.out.print("英语：");

                double english = Double.parseDouble(reader.readLine());

                stu = new Student(name, id, literature, math, english);

                totals.getTotal();

                map.put(stu.getTotal(), i);

            } catch (Exception e) {

                //TODO: handle exception

                e.printStackTrace();

            }

        }

        Arrays.sort(totals);

        for (int j = stuNum - 1; j 》= 0; j--) {

            int i = map.get(totals);

            System.out.println(stu.toString());

        }

    }

}

2、Student类

public class Student  {

private String name;

    private int stuId;

    //总分

    private double total;

    private double english;

    //数学

    private double mathematical;

    //文学

    private double literature;

public String getName(){

return name;

}

public void SetName(String name)    {

this.name = name;

}

    public int getStuId() {

        return stuId;

    }

    public void setStuId(int stuId) {

        this.stuId = stuId;

    }

    public int getGrade() {

        return grade;

    }

    public void setGrade(int grade) {

        this.grade = grade;

    }

    public Student() {

    }

    public double getTotal() {

        return this.english + this.literature + this.mathematical;

    }

    public double getEnglish() {

        return english;

    }

    public void setEnglish(double english) {

        this.english = english;

    }

    public double getMathematical() {

        return mathematical;

    }

    public void setMathematical(double mathematical) {

        this.mathematical = mathematical;

    }

    public double getLiterature() {

        return literature;

    }

    public void setLiterature(double literature) {

        this.literature = literature;

    }

    public Student(int stuId, double total, double english, double mathematical, double literature) {

        this.stuId = stuId;

        this.total = total;

        this.english = english;

        this.mathematical = mathematical;

        this.literature = literature;

    }

    public Student(String name, int stuId, double english, double mathematical, double literature) {

        this.name=name;

        this.stuId = stuId;

        this.english = english;

        this.mathematical = mathematical;

        this.literature = literature;

    }

    @Override

    public String toString() {

        return "学生 " + name + "，学号 " + stuId + "，总分 =" + getTotal() + " [英语=" + english + ", 语文="

                + literature + ", 数学=" + mathematical + "]";

    }

}

3、运行效果

用java编写一个学生类，学生有学号，姓名，专业，年龄，性别等属性，

public class Student {
String xuehao;
String xingming;
String zhuanye;
int nianling;
String xingbie;
void xuexi() {
System.out.println("学习");
}
void chifan() {
System.out.println("吃饭");
}
}

怎么编写一个简单Java应用程序，输出自己的姓名和学号

下面是一个java 小程序实现的\x0d\x0aimport java.awt.*;//引入包\x0d\x0aimport java.applet.Applet;//引入包\x0d\x0apublic class Output extends Applet//定义类\x0d\x0a{\x0d\x0a //定义变量\x0d\x0a private String name;\x0d\x0a private int num;\x0d\x0a //初始化\x0d\x0a public void init()\x0d\x0a {\x0d\x0a name = getParameter("vname");\x0d\x0a num = Integer.parseInt(getParameter("vnum"));\x0d\x0a }\x0d\x0a //输出\x0d\x0a public void paint(Graphics g)\x0d\x0a {\x0d\x0a g.drawString ("姓名："+name+"；学号："+num,20,30);\x0d\x0a }\x0d\x0a}\x0d\x0a\x0d\x0a相应的html文件\x0d\x0a\x0d\x0a\x0d\x0a

\x0d\x0a

\x0d\x0a\x0d\x0a

使用Java语言，造100条大学生的基本信息（学校，专业，姓名，学号）

import java.util.Random;
public class D1 {
public static void main(String args) {
String name = "";
String zy = "";
for (int i = 0; i 《 100; i++) {
name = getXS();
zy = getJob();
System.out.println("学校：xxxx大学              姓名："+name+"                专业："+zy+"        学号："+(i+1001));
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
public static String getJob() {
String arr = {"软件工程","多媒体","计算机科学与技术","网络工程"};
Random r = new Random();
return arr;
}

编写java程序实现以下功能:从键盘输入学生姓名、学号、成绩，并保存到文本文件中，重复进行直到遇到空格符

public class test3{
public static void main(String args) {
String FilePath="d:\\javaTest\\output.txt";
writeAll(FilePath);
}
private static void writeAll(String filePath) {
File output = new File(filePath);
String outputStr = "";
Scanner sc = new Scanner(System.in);
System.out.println("请输入信息：");
while (true) {
String str = sc.nextLine();
if (str == null || "".equals(str)) {
System.err.println("退出\n\n");
break;
}
outputStr += str + "\r\n";
}
FileWriter fw = null;
BufferedWriter bw = null;
try {
fw = new FileWriter(output, true);
bw = new BufferedWriter(fw);
bw.write(outputStr);
System.out.println("您输入的信息(姓名，学号，成绩)：\n" + outputStr + "\n已写入：" + filePath);

} finally {
try {
bw.flush();
fw.flush();
bw.close();
fw.close();
} catch (IOException e) {
e.printStackTrace();

编写一个java程序,要求输入自己的学号姓名

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class Test222 {

str = new BufferedReader(new InputStreamReader(System.in));
System.out.println("请输入姓名：");
a = str.readLine();
System.out.println("姓名为：" + a);

java编写一个学生类,描述学生的学号,姓名,成绩.学号用整型,成绩用浮点型,姓名用Str

class Student {
private String name;
private int stuId;
private float score;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getStuId() {
return stuId;
}
public void setStuId(int stuId) {
this.stuId = stuId;
}
public float getScore() {
return score;
}
public void setScore(float score) {
this.score = score;
}
public void showInfo() {
System.out.println("Student ");
}
}

用java创建一个学生类，包括学号，姓名，成绩，然后构造方法，初始化，输出学生的基本信息

public class Student {
private String name;
private String number;
private int score;
public Student() {
}
public Student(String name, String number, int score) {
super();
this.name = name;
this.number = number;
this.score = score;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
public int getScore() {
return score;
}
public void setScore(int score) {
this.score = score;
}
public String toString() {
return "Name: " + name
+ ",Number: " + number
+ ",Score : " + score;
}
//调用方法
public static void main(String args) {
Student s = new Student("Jack","123456",98);
System.out.println(s.toString());
}
}

运行结果：

Name: Jack,Number: 123456,Score : 98

怎么用java编写一个打印三角乘法表的程序，程序名为A1，并打印输出自己的学号和名字

public static void main(String args)
{
String studentNumber = "你的学号";
String studentName = "你的名字";
System.out.println("学号：" + studentNumber + ",姓名：" + studentName);
for (int i = 1; i 《= 9; i++)
{
for (int j = 1; j 《 i + 1; j++)
{
System.out.print(j + "*" + i + "=" + i * j + "\t");
}
System.out.println();
}
}

你把学号和名字改成你自己的就可以了。

希望可以帮到你，望采纳~
