java基础题挂了~~

Question

跟着老湿写的，为什么我的会编译报错，提示主函数中的三个new语句cannot be referenced from static context,我是抄的，他的都没有编译失败。好奇怪，到底哪里错了，谢谢

```java
package homework;

public class HomeWork01 {
    public static void main(String[] args) {
        Person[] persons = new Person[3];
        persons[0] = new Person("maomao", 7, "dataengineer");
        persons[1] = new Person("huic", 37, "java");
        persons[2] = new Person("daoda", 35, "train");
        for (int i = 0; i < persons.length; i++) {
            System.out.println(persons[i]);
        }
        System.out.println("排序后：======================");
        Person temp = null;
        for (int i = 0; i < persons.length-1; i++) {
            for (int j = 0; j < persons.length - i - 1; j++) {
                if (persons[j].getJob().length() > persons[j + 1].getJob().length()) {
                    temp = persons[j];
                    persons[j] = persons[j + 1];
                    persons[j + 1] = temp;
                }

            }

        }
        for (int i = 0; i < persons.length; i++) {
            System.out.println(persons[i].toString());
        }
    }

     class Person {
       private String name;
        private int age;
        private  String job;

        public Person(String name, int age, String job) {
            this.name=name ;
            this.age=age;
            this.job=job;
        }

        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 String getJob() {
            return job;
        }

        public void setJob(String job) {
            this.job = job;
        }

        @Override
        public String toString() {
            return "Person{" +
                    "name='" + name + '\'' +
                    ", age=" + age +
                    ", job='" + job + '\'' +
                    '}';
        }
    }
}

Answer 1

你错了一个大括号}把Person 写成了HomeWork01的内部类。就是HomeWork01结尾的}位置错了，应该在Person前面
应该是

public class HomeWork01 {
}
class Person {
}

而你写成了
public class HomeWork01 {

class Person {
}
}
