Setter，Getter方法

public class Student {

    System.out.println(name+","+age);
    }
}

public class TestStudent {
    public static void main(String[] args) {
        //创建对象(因为private只能在自己的类中识别)
        Student student = new Student();
        //给set属性赋值
    student.setAge(18);
    student.setName("顺");
        //调用方法
        student.show();

        System.out.println(student.getName()+"----"+student.getAge());
