編寫一個名為 inputBirthday 的方法，該方法接受控制臺的掃描儀作為參數，并提示用戶輸入出生月份、日期和年份，然后以合適的格式打印出生日期。下面是與用戶的對話示例：我需要像這樣接受這個輸入 -你出生在一個月中的哪一天？8你出生的月份叫什么名字？五月你出生在哪一年？1981輸出應該是這樣的——您出生于1981年5月8日。你老了！

public static void inputBirthday(Scanner input) {
Scanner start = new Scanner(System.in);
System.out.print("On what day of the month were you born? ");
int day = input.nextInt();
System.out.print("What is the name of the month in which you were born? ");
String month = input.next();
System.out.print("During what year were you born? ");
int year = input.nextInt();
System.out.println("You were born on " + month + " " + day + "," + " " + year + "." + " You're mighty old!");

public static void main(String[] args) {

// either instantiate the enclosing class, or make inputBirthday static
inputBirthday(in);

public static void inputBirthday(Scanner abc)
{
System.out.print("On what day of the month were you born? ");
int inputDay = abc.nextInt();
System.out.print("What is the name of the month in which you were born? ");
String inputMonth = abc.next();
System.out.print("During what year were you born? ");
int inputYear = abc.nextInt();
System.out.println("You were born on " + inputMonth + " " + inputDay + "," + " " + inputYear + "." + " You're mighty old!");
}
最后它工作了，代碼通過了所有測試

我認為問題在于，要求明確規定你要編寫一個名為接受對象的方法。您已經編寫了一個方法，然后編寫了一個正在接受 的方法。inputBirthdayScannermaininputBirthdayString, int, int
將代碼從方法移動到方法，刪除掃描儀實例化，并修改方法以接受掃描儀（可能是 .maininputBirthdayinputBirthdayinputBirthday(Scanner abc)
編寫的代碼在 intellij 中工作，因為它是一個完整的程序。但對于網站，他們希望有一個特定的方法簽名。這種方法與此類在線代碼位置所期望的沒有什么不同。leetcode
OP進行了編輯，但同樣，要求規定該方法應如下所示：
public void inputBirthday(Scanner abc) {
System.out.println("On what day of the month were you born? ");
int inputDay = abc.nextInt();
System.out.println("What is the name of the month in which you were born? ");
String inputMonth = abc.next();
System.out.println("During what year were you born? ");
int inputYear = abc.nextInt();
System.out.println("You were born on " + inputMonth + " " + inputDay + "," + " " + inputYear + "." + " You're mighty old!");
}
所以，再次：
獲取方法簽名以匹配要求（不清楚它是否應該是靜態的，因此可能需要是）。public static inputBirthday(Scanner abc)
不要在方法中實例化掃描儀。inputBirthday
要從 IDE 進行測試，請執行以下操作：
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
// either instantiate the enclosing class, or make inputBirthday static
inputBirthday(in);
}
