Class Java找不到类的方法

java给了我一个错误
Java\Workspace\PROJECTS\Farm\animalLab.Java[第15行] 错误：找不到符号 符号：

methodaddanimal（java.lang.String，int，Farm[]）

位置：农场[]类型的可变农场

 class Farm{
public String animal = null;

public Farm(String s){
animal = s;

   public String getAnimal(){
return animal;

我的代码是

import java.util.Scanner;

class animalLab{
   public Farm[] farm = new Farm[1000];

public void main(String[]args){
Scanner reader = new Scanner(System.in);
int i = 0;

while(reader.hasNext()){
  if(reader.nextLine() == "Quit")
    break;
  if(reader.nextLine()=="Add"){
    System.out.println("Enter animal to add: ");
    String add = reader.nextLine();
    farm.addAnimal(add, i, farm);
  }

 class Farm{
public String animal = null;

public Farm(String s){
animal = s;

   public String getAnimal(){
return animal;

我的农场课看起来像这样

 class Farm{
public String animal = null;

public Farm(String s){
animal = s;

   public String getAnimal(){
return animal;

}

 class Farm{
public String animal = null;

public Farm(String s){
animal = s;

   public String getAnimal(){
return animal;

}

 class Farm{
public String animal = null;

public Farm(String s){
animal = s;

   public String getAnimal(){
return animal;

public void addAnimal（字符串add，int i，Farm[]）{
for（int x=0；x
farm
是（许多）场对象的数组

 class Farm{
public String animal = null;

public Farm(String s){
animal = s;

   public String getAnimal(){
return animal;

数组没有
addAnimal
方法。请花时间仔细阅读错误消息

 class Farm{
public String animal = null;

public Farm(String s){
animal = s;

   public String getAnimal(){
return animal;

像这样看

 class Farm{
public String animal = null;

public Farm(String s){
animal = s;

   public String getAnimal(){
return animal;

错误：找不到[addAnimal]方法

 class Farm{
public String animal = null;

public Farm(String s){
animal = s;

   public String getAnimal(){
return animal;

位置：农场[]类型的可变农场[其]

 class Farm{
public String animal = null;

public Farm(String s){
animal = s;

   public String getAnimal(){
return animal;

考虑到
farm[x].animal
“工作”（表达式
farm[x]
属于
farm
）类型——如何使用它来修复编译错误

 class Farm{
public String animal = null;

public Farm(String s){
animal = s;

   public String getAnimal(){
return animal;

我建议以复数形式命名数组/集合的变量，例如，
farms
，以减轻这种混淆。此外，除非需要使用数组（如家庭作业），否则我建议使用-，这样可以更轻松地添加和迭代项

 class Farm{
public String animal = null;

public Farm(String s){
animal = s;

   public String getAnimal(){
return animal;

快乐编码

 class Farm{
public String animal = null;

public Farm(String s){
animal = s;

   public String getAnimal(){
return animal;
