定义Student类-CFANZ编程社区

1 问题

定义一个Student类，属性有学号，姓名，年龄，性别，语文成绩，数学成绩，英语成绩。

2 方法

创建两个学生对象，并给属性赋值和调用方法学习，考试(打印输出学习,考试即可)

public class Test1Student { public void main(String[] args){ Test1Student stu1 = new Test1Student(); Test1Student stu2 = new Test1Student(); stu1.num=110; stu1.name="张三"; stu1.age=18; stu1.sex = '男'; stu1.chinese = 96; stu1.math = 97; stu1.english = 99; stu1.learn(); stu1.exam(); stu2.num=111; stu2.name="李四"; stu2.age=17; stu2.sex = '女'; stu2.chinese = 94; stu2.math = 93; stu2.english = 92; stu2.learn(); stu2.exam(); } //属性 int num; String name; int age; char sex; int chinese; int math; int english; //方法--->学习 public void learn(){ System.out.println("学号:"+num+"\n"+"姓名:"+name+"\n"+"性别:"+sex+"\n"+"语数英成绩为"+chinese+"\t"+math+"\t"+english+"\n"+"好好学习!"); } //方法--->考试 public void exam(){ System.out.println("认真考试!"); } } }

public class Test1Student {
    public void main(String[] args){
        Test1Student stu1 = new Test1Student();
        Test1Student stu2 = new Test1Student();
        stu1.num=110;
        stu1.name="张三";
        stu1.age=18;
        stu1.sex = '男';
        stu1.chinese = 96;
        stu1.math = 97;
        stu1.english = 99;
        stu1.learn();
        stu1.exam();
        stu2.num=111;
        stu2.name="李四";
        stu2.age=17;
        stu2.sex = '女';
        stu2.chinese = 94;
        stu2.math = 93;
        stu2.english = 92;
        stu2.learn();
        stu2.exam();
    }
    //属性
    int num;
    String name;
    int age;
    char sex;
    int chinese;
    int math;
    int english;
    //方法--->学习
    public void learn(){
        System.out.println("学号:"+num+"\n"+"姓名:"+name+"\n"+"性别:"+sex+"\n"+"语数英成绩为"+chinese+"\t"+math+"\t"+english+"\n"+"好好学习!");
    }
    //方法--->考试
    public void exam(){
        System.out.println("认真考试!");
    }
 }
 }

3 结语

针对如何定义一个student类的问题，提出通过利用创建两个学生对象，并给属性赋值和调用方法，通过java的编程实验，证明该方法是有效的。
