我試圖將 int 的用戶輸入與 String 數組進行比較。import java.util.Arrays;import java.util.Scanner;public class Array{ public static void main(String[]args) { Scanner input = new Scanner(System.in); int number; String [] month = new String[13]; month[0] = "Null"; month[1] = "January"; month[2] = "February"; month[3] = "March"; month[4] = "April"; month[5] = "May"; month[6] = "June"; month[7] = "July"; month[8] = "August"; month[9] = "September"; month[10] = "October"; month[11] = "November"; month[12] = "December"; System.out.println("Enter a number"); number = input.nextInt(); }}

只需使用 input 作為索引，假設他們輸入 1 為一月，那么您可以調用索引：
System.out.println("You've selected the month of: " + month[number]);將為 輸出“一月”，當然month[number]，您還必須檢查是否超出范圍。

試試這個
System.out.println("Please enter a number between 0 and 13");
Integer userNmber = input.nextInt();
if(userNmber > month.length-1){
System.out.println("Please enter a number between 0 and 13");
userNmber = input.nextInt();
}
if(month[userNmber] != null)
System.out.println("Input from user " + userNmber + " match with month : "+ month[userNmber]);
