Java面向对象之创建和使用对象——定义学生/教师类并输出相关信息

大家好，又见面了，我是你们的朋友全栈君。

学生类

import java.util.Scanner;

public class Student { 
   

    String name = "张三";
    int age = 16;
    String grade = "三年二班" ;
    String fancy = "打篮球 唱歌 读书 冒险";

    public void introduce(){ 
   

        System.out.println("-----------------------------------------------------");
        System.out.println("姓名：" + name + "\n年龄：" + age + "\n班级：" + grade);
        System.out.println("兴趣爱好：" + fancy);
    }

    public void init(){ 
   

        Scanner sc = new Scanner(System.in);
        System.out.print("请输入姓名：");
        name = sc.nextLine();
        System.out.print("请输入年龄：");
        age = sc.nextInt();
        System.out.print("请输入班级：");
        grade = sc.next();
        System.out.print("请输入兴趣爱好：");
        fancy = sc.next();
    }

    public static void main(String[] args){ 
   

        Student student = new Student();
        student.init();
        student.introduce();

    }
}

教师类，输出教师相关信息

import java.util.Scanner;

public class Teacher { 
   

    String name = "李四";
    int age = 10;
    String major = "计算机视觉" ;
    String course = "计算机网络 操作系统 数据结构 数据库";

    public void introduce(){ 
   

        System.out.println("-----------------------------------------------------");
        System.out.println("姓名：" + name + "\n教龄：" + age + "年\n专业方向：" + major);
        System.out.println("教授课程：" + course);
    }

    public void init(){ 
   

        Scanner sc = new Scanner(System.in);
        System.out.print("请输入姓名：");
        name = sc.nextLine();
        System.out.print("请输入教龄：");
        age = sc.nextInt();
        System.out.print("请输入专业方向：");
        major = sc.next();
        System.out.print("请输入教授课程：");
        course = sc.next();
    }

    public static void main(String[] args){ 
   

        Teacher teacher = new Teacher();
        //teacher.init();
        teacher.introduce();

    }
}
