配列に値を割り当てる方法は？

Question

私はハンバーガーオブジェクトを作成しようとしています。トッピングなどの配列を持たなければなりません。各オブジェクトの配列に値を代入しようとするたびにコンパイルエラーが発生します。ここではクラスは任意のヘルプは高く評価され

/* 
This Hamburger class is to define how to make a Hamburger sandwich 
Then this class will be used to create a Hamburger object in the tester class 

Fields & their purpose 
4. toppings – an array of Strings storing the toppings on the burger. 

*/ 
public class Hamburger { 

    //declear private fields 
    private int weight; 
    private String doneness; 
    private boolean cheese; 
    private String[] toppings; 

     //creat arrays for each object, then use it in each specific object 
     //String[] hamburgerToppings = {"l", "m"}; 
     //String[] cheseburgerToppings = {"l", "m"}; 
     //String[] anotherCheseburgerToppings = {"l", "m"}; 


    //create printable array of toppings 


    //full constructor 
    public Hamburger(int weightOZ, String done, 
        boolean WantCheese, String[] topps) {  
     weight = weightOZ; 
     doneness = done; 
     cheese = WantCheese; 
     toppings = topps; 
     } 

    //overloaded no-arg constructor 
    public Hamburger(){ 

    } 

    //copy constructor 
    public Hamburger(Hamburger burger){  
     weight = burger.weight; 
     doneness = burger.doneness; 
     cheese = burger.cheese; 
     toppings = burger.toppings;  
    } 

    //declear getter methods 
    public int getWeight() { 
     return weight; 
} 
    public String getDoneness() { 
     return doneness; 
} 

、ここでは、テスタークラスは

//This class will test & run the Hamburger class 
//It has the main method to run the other methods in the Hamburger class 
public class HamburgerTester { 

    public static void main(String[] args) { 

     //Creating Hamburger objects 
     Hamburger hamburger = new Hamburger(); 
     Hamburger cheseburger = new Hamburger(); 
     Hamburger anotherCheseburger = new Hamburger(cheseburger); 

     //Setting Values for hamburger object 
     hamburger.setWeight(7); 
     hamburger.setDoneness("Mediuem Rare"); 
     hamburger.setCheese(false); 
     hamburger.setToppings(); 

     //Setting Values for cheseburger object 
     cheseburger.setWeight(10); 
     cheseburger.setDoneness("Well Done"); 
     cheseburger.setCheese(true); 
     //cheseburger.setToppings(); 

     //anotherCheseburger object is a copy of cheseburger 
     //there's no need to set special values for it 

     //Printing Results 
     System.out.println("Hamburger weight is: " + hamburger.getWeight() + 
         " doneness: " + hamburger.getDoneness() + 
         " with/without cheese: " + hamburger.getCheese() + 
         " Toppings: " + hamburger.getToppings()); 

     System.out.println("cheseburger: " + cheseburger.toString()); 
     System.out.println("cheseburger copy: " + anotherCheseburger.toString()); 
     System.out.println("cheseburger wieght after a bite: " + cheseburger.bite()); 
     System.out.println("cheseburger wieght after a 2 bites: " + cheseburger.bite());   
    } 
} 

    public boolean getCheese() { 
     return cheese; 
} 
    public String[] getToppings() { 
     return toppings; 
} 


    //declear setter methods 
    public void setWeight(int weightOZ) { 
     this.weight = weightOZ; 
} 
    public void setDoneness(String done) { 
     this.doneness = done; 
} 
    public void setCheese(boolean WantCheese) { 
     this.cheese = WantCheese; 
} 
    public void setToppings(String[] topps) { 
     this.toppings = topps;   
     for(int i =0; i < toppings.length; i++) { 
     if (i > 0) 
      System.out.print(", ");   
     System.out.print(toppings[i]); 
     } 
} 


    //copy method 
    public Hamburger copy(){ 
    Hamburger burger = new Hamburger(weight, doneness, cheese, toppings); 
    return burger;  
    } 

    //bite methode 
    public int bite(){ 
     if (weight > 0) 
      weight--;  
     return weight; 
    } 

    //toString method to print what each Hamburger contains 
    public String toString(){ 

    String str = "Weight is: " + weight + 
        "\nDoneness is: " + doneness + 
        "\nCheese is: " + cheese + 
        "\nToppings are: " + toppings;    
     return str; 
    } 
} 

だだ、ありがとう！

私は何をしようとしていますか？オブジェクトHamburgerのゲッターメソッドとセッターメソッドは、Hamburgertesterクラスのように見えます。
