java学习-简单的代码-全属性的构造方法和study方法返回

public class Student {
    private String name;
    private int age;
    private String sex;
    private String grade;

    public Student(String name1,int age1,String sex1,String grade1){
        this.name= name1;
        this.age=age1;
        this.sex=sex1;
        this.grade=grade1;
    }

    public String study(String name){
        String chengji =name + "chengjiyouxiu";
        return chengji;
    }
    public static void main( String[] args ) {
        Student stu = new Student("张三",19,"男","高二");
        System.out.println(stu.name);
        stu.study(stu.name);
        String aa = stu.study(stu.name);
        System.out.println(aa);



    }
}



定义了属性，添加一个全属性的构造方法和一个study的方法返回。
特别注意带参数的构造方法。
