实现代码如下：

Student类：

public class Student {
private String name;
private String sex;
private int age;
private double chinese;
private double math;
private double english;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getSex() {
return sex;
}

public void setSex(String sex) {
this.sex = sex;
}

public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}

public double getChinese() {
return chinese;
}

public void setChinese(double chinese) {
this.chinese = chinese;
}

public double getMath() {
return math;
}

public void setMath(double math) {
this.math = math;
}

public double getEnglish() {
return english;
}

public void setEnglish(double english) {
this.english = english;
}
}

-----------------------------------------------------------------

StudentTest类：（测试类）

import java.util.Scanner;

public class StudentTest {
public static void main(String[] args) {
Student student = new Student();
Scanner sc = new Scanner(System.in);
System.out.println("请输入姓名：");
student.setName(sc.next());
System.out.println("请输入性别：");
student.setSex(sc.next());
System.out.println("请输入年龄：");
student.setAge(sc.nextInt());
System.out.println("请输入语文成绩、数学成绩、英语成绩：");
student.setChinese(sc.nextDouble());
student.setMath(sc.nextDouble());
student.setEnglish(sc.nextDouble());
Double count = student.getChinese()+ student.getMath()+student.getEnglish();
System.out.println("姓名："+student.getName()+" 性别："+student.getSex()+" 年龄："+student.getAge());
System.out.println("总分："+count+" 平均分："+count/3);
}
}

运行结果为：

int a,b,c,d,f;

f=in.nextInt();
Student stu=new Student(a,name,e,b,c,d,f);
stu.shuchu(a,name,e);
stu.chengji(b, c, d, f);
}
}}

class Student{

private int 学号;
private String 姓名;
private char 性别;
private int 高数;
private int 英语;
private int c语言;
private int Java语言;
public Student(int 学号,String 姓名,char 性别,int 高数,int 英语,int c语言,int Java语言)
{
this.c语言=c语言;
this.Java语言=Java语言;
this.姓名=姓名;
this.学号=学号;
this.性别=性别;
this.英语=英语;
this.高数=高数;
}
public void shuchu(int 学号,String 姓名,char 性别)
{
System.out.print(学号+" "+姓名+" "+性别);
}
public void chengji(int 高数,int 英语,int c语言,int Java语言)
{
System.out.print(" "+高数+" "+英语+" "+c语言+" "+Java语言+" ");
System.out.println((高数+英语+c语言+Java语言)/4+" "+(高数+英语+c语言+Java语言));
}}
