私のプログラム全体は以下のとおりです。
私が抱えている問題は、この特定のコード行によって生成されたエラー メッセージによって stdout があふれてしまうことです。
for(int x = 0; x < 3; x++)
{
for(int xx = 0; xx < 6; xx++)
{
if(toppings[x].equalsIgnoreCase(validToppings[xx]))
{price += 0.75;} else {System.out.println("Error in Pizza class: Attempt to set invalid pizza topping " + toppings[x]);};
}
}
完成に多くの時間を費やしたコードを書き直すつもりはありませんが、簡潔なエラー メッセージを表示するために switch ステートメントなどを使用する必要がある場合は、書き直します。私の現在の方法が最善だと思いますが。
以下は、クラスのテストです。
public class TestPizza
{
public static void main(String args[])
{
int x;
String t1[] = {"Mushrooms", "Onions", ""};
String t2[] = {"Pepperoni", "Mushrooms", ""};
String t3[] = {"Pepperoni", "Mushrooms", "Onions"};
String t4[] = {"Sausage", "", ""};
Pizza one = new Pizza();
Pizza two = new Pizza();
Pizza three = new Pizza();
Pizza four = new Pizza();
one.setSize(12);
one.addTopping(t1);
one.showValues();
two.setSize(8);
two.addTopping(t2);
two.showValues();
three.setSize(16);
three.addTopping(t3);
three.showValues();
four.setSize(20);
four.addTopping(t4);
four.showValues();
}
}
これがクラスです。
