編寫一個(gè)名為 inputBirthday 的方法，該方法接受控制臺(tái)的掃描儀作為參數(shù)，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(duì)話示例：我需要像這樣接受這個(gè)輸入 -你出生在一個(gè)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(yīng)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 inputBirthday(Scanner abc)

int inputDay = abc.nextInt();
System.out.print("What is the name of the month in which you were 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(guò)了所有測(cè)試

我認(rèn)為問(wèn)題在于，要求明確規(guī)定你要編寫一個(gè)名為接受對(duì)象的方法。您已經(jīng)編寫了一個(gè)方法，然后編寫了一個(gè)正在接受 的方法。inputBirthdayScannermaininputBirthdayString, int, int
將代碼從方法移動(dòng)到方法，刪除掃描儀實(shí)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?yàn)樗且粋€(gè)完整的程序。但對(duì)于網(wǎng)站，他們希望有一個(gè)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(méi)有什么不同。leetcode
OP進(jìn)行了編輯，但同樣，要求規(guī)定該方法應(yīng)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(yīng)該是靜態(tài)的，因此可能需要是）。public static inputBirthday(Scanner abc)
不要在方法中實(shí)例化掃描儀。inputBirthday
要從 IDE 進(jìn)行測(cè)試，請(qǐng)執(zhí)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);
}
