英文:
I am making a pizza program that asks for the the user's choice of pizza, the size, the toppings and if they want delivery or not. However, I am facing a problem where I input something into the console as input but I don't receive any response. I have included the code.
My Code:
public static void main(String[] args) throws Exception {
System.out.println("Welcome to Zayann's Pizza");
Scanner myPizza = new Scanner(System.in);
System.out.println("What pizza would you like? 1) cheese 2) chicken 3) beef 4) veg-- Please enter number");
String[] pizzaSize = {"6 inch", "9 inch", "12 inch", "15 inch", "20 inch"};
String[] pizza = {"cheese","chicken","beef","veg"};
String pizzaOrder = myPizza.nextLine();
if (myPizza.equals(pizza[0])) {
System.out.println("You have selected cheese");
System.out.println("What size would you like? 6 inch, 9 inch, 12 inch, 15 inch,20 inch-- Please enter size");
}
}

你正在尝试将一个Scanner（myPizza）与一个字符串（pizza[0]）进行比较。
正如 @azro 所说，请粘贴您的代码，而不是上传您的图片。
英文:
You are trying to compare a Scanner (myPizza) with a String (pizza[0]).
And how @azro say, please paste your code, not upload your image.

你不应该将Scanner对象与String进行比较，尝试使用以下代码：
public static void main(String[] args) throws Exception {
System.out.println("欢迎光临Zayann's披萨");
Scanner myPizza = new Scanner(System.in);
System.out.println("您想要什么披萨？ 1) 芝士披萨 2) 鸡肉披萨 3) 牛肉披萨 4) 素食披萨-- 请输入数字");
String[] pizzaSize = {"6英寸", "9英寸", "12英寸", "15英寸", "20英寸"};
String[] pizza = {"芝士披萨","鸡肉披萨","牛肉披萨","素食披萨"};
String pizzaOrder = myPizza.nextLine();
if (pizzaOrder.equals(pizza[0])) {
System.out.println("您选择了芝士披萨");
System.out.println("您想要什么尺寸？ 6英寸、9英寸、12英寸、15英寸、20英寸-- 请输入尺寸");
String pizzaEnterSize = myPizza.nextLine();
if (pizzaEnterSize.equals(pizzaSize[0])) {
System.out.println("您选择了6英寸尺寸");
}
}
}
英文:
You should not to compare a Scanner object with String，try the follow code：
public static void main(String[] args) throws Exception {
System.out.println("Welcome to Zayann's Pizza");
Scanner myPizza = new Scanner(System.in);
System.out.println("What pizza would you like? 1) cheese 2) chicken 3) beef 4) veg-- Please enter number");
String[] pizzaSize = {"6 inch", "9 inch", "12 inch", "15 inch", "20 inch"};
String[] pizza = {"cheese","chicken","beef","veg"};
String pizzaOrder = myPizza.nextLine();
if (pizzaOrder.equals(pizza[0])) {
System.out.println("You have selected cheese");
System.out.println("What size would you like? 6 inch, 9 inch, 12 inch, 15 inch,20 inch-- Please enter size");
String pizzaEnterSize = myPizza.nextLine();
if (pizzaEnterSize.equals(pizzaSize[0])) {
System.out.println("You chose 6 inch size");
}
}
}
