JAVA：Non-static field 'p2' cannot be referenced from a static context报错


public class Test {
    Person p1 = new Person("lzh",34,'m');
    Person p2 = new Person("lzh",34,'m');
    public static void main(String[] args){
        System.out.println(p1.equals(p2)); //为什么提示：Non-static field 'p2' cannot be referenced from a static context？
    }
}

class Person{
    private String name;
    private  int age;
    private char gender;

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

    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 char getGender() {
        return gender;
    }

    public void setGender(char gender) {
        this.gender = gender;
    }
}

main函数内p1,p2报错Non-static field 'p2' cannot be referenced from a static context
之前这样写都没有问题，突然间每次写都报错，是我的设置问题，还是代码问题？

p1,p2放main方法里边就好了，类中的变量不能直接在main方法中使用
