在詢問切換器的輸入之前，字符串 asd 打印雙倍，我現(xiàn)在感到絕望。我希望字符串“asd”只打印一次，但在我的情況下打印兩次，我的猜測是錯誤或循環(huán)，抱歉，我是這里的新手，對編程很陌生public class FruitBasket {static String option;static String choice1;static int catcher;static int counter1 = 1;static int counter = 0;static String eater = "e";static Scanner sc = new Scanner(System.in);       static Stack<String> basket = new Stack();static String switcher;public static void main(String[] args) {    catching();}static void catching(){    System.out.println("Catch and eat any of these fruits: " + "'apple', 'orange', 'mango', 'guava'" );    System.out.println("A apple, O orange, M mango, G guava");    System.out.print("How many fruits would you like to catch? ");    catcher = sc.nextInt();    switches();     }     static void switches(){    while(counter1 < catcher)  {    String asd = "Fruit " + counter1 + " of " + catcher + ":";    System.out.print(asd);    switcher = sc.nextLine();         switch (switcher) {            case "a":                basket.push("apple");                counter++;                counter1++;                break;
