Java程序这个程序错误了不知道怎么改

Student01 stu1 = new Student01("张三",18);不是点，是空格

public class Student {

    public static void main(String[] args) {
        Student01 stu1 = new Student01("张三",18);
        Student01 stu2 = new Student01("李四",19);
        Student01 stu3 = new Student01("王五",20);

        stu1.setAge(20);
        stu2.setName("小明");
        Student01.setSchool("B大学");
        stu1.info();
        stu2.info();
        stu3.info();



    }

    static class Student01{
        private String name;
        private int age;
        //注意：非静态内部类static不能用于内部类的属性
         private static  String school ="A大学";
        public Student01(String name, int age) {
            this.name = name;
            this.age = age;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public int getAge() {
            return age;
        }

        public void setAge(int age) {
            this.age = age;
        }

        public static String getSchool() {
            return school;
        }

        public static  void setSchool(String school) {
            school = school;
        }

        public void info(){
            System.out.println("姓名："+this.name+",年龄:"+this.age+",学校:"+this.school);
        }
    }

}
