今天的JAVA，学习的是关于类与对象的知识

不得不说学了C++再来接触这个还挺舒服的，下面是我今天试着写的一个学生类

package hellopeace;

public class Student {
    public String Name; 
    public int Age;
    private boolean Sex; 
    public boolean isSex() {
        return Sex;
    }
    public void setSex(boolean sex) {
        this.Sex = sex;
    }
    public static void main(String[] args) {
        Student ma = new Student();
        ma.Name = "马云 ";
        String isMan = ma.isSex() ? "女" : "男";
        ma.Age = 55;
        System.out.println("姓名：" + ma.Name + "性别：" + isMan + "年龄：" + ma.Age);
        Student dong = new Student();
        dong.Name = "董明珠 ";
        dong.Sex = true;
        dong.Age = 65;
        String isWoman = dong.isSex() ? "女" : "男";
        System.out.println("姓名：" + dong.Name + "性别：" + isWoman + "年龄：" + dong.Age);
    }
}

运行结果
