这个作业是英文版的，英文好的给看看吧！！
Develop a program that implements(实现) a cookbook. We are providing(提供) a general description（种类） of the classes associated（关联） with this design. Feel free to add any methods/data members （成员）you understand are necessary. Try to practice the following concepts as you develop the implementation:
One-dimensional array of objects（一维数组对象）
get/set methods for classes（给类设置方法）
private vs. public access specifiers（private和public接口说明）
Passing primitives and objects as parameters（原始和对象参数传递）
I. Recipe(食谱) class - represents a cooking recipe.（代表烹饪食谱）
---------------
data members:
1. name - name associated with the recipe (e.g. "YuXiangRouSi")
2. Instructions（操作指南） - an array of String objects where each entry represents one
instruction associated with the recipe.
3. numberOfInstructions - integer representing the number of instructions（操作指南的数量）
4. Ingredients（配料） - an array of String objects where each entry represents an ingredient(字符串数组表示参加的配料)
5. numberOfIngredients - integer representing the number of ingredients methods:
1. Appropriate(适当的) constructor
2. get/set methods you understand are necessary
3. toString() method
4. public boolean equals(Object obj) --- to compare two Recipes and return true if the two Recipes have same contents.（比较两个食谱如果内容相等返回真）
II. Cookbook - represents the collection of recipes（代表收集的食谱）
-------------
data members:
1. listOfRecipes - an ArrayList of Recipe objects
2. numberOfRecipes - an integer representing the number of recipes（代表int型recipes数量）
methods:
1. Appropriate（适当的） constructor
2. get/set methods you understand are necessary
3. public void addRecipe (Recipe r) - adds the recipe to the list.
You must keep the recipes ordered(安排好) by recipe name.
4. public Recipe findRecipe( String recipeName) - locates（找出） a recipe based on a recipe name.
5. public void removeRecipe(String name) - deletes a recipe from the cookbook.
6. public string toString( ) - implement the appropriate toString method（实施适当的toString()方法）
7. main - write a main method that tests your class and show how your methods work.
