Java输入相应月份的数字时，打印出相应月份的英文

当你在Java中编写程序，想要根据用户输入的月份数字对应输出英文名称时，可以创建一个方法来实现这个功能。这里是一个简单的示例：

import java.util.Scanner;

public class MonthConverter {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("请输入月份数字（1-12）:");
        int monthNumber = scanner.nextInt();

        String monthName;
        switch (monthNumber) {
            case 1:
                monthName = "January";
                break;
            case 2:
                monthName = "February";
                break;
            case 3:
                monthName = "March";
                break;
            case 4:
                monthName = "April";
                break;
            case 5:
                monthName = "May";
                break;
            case 6:
                monthName = "June";
                break;
            case 7:
                monthName = "July";
                break;
            case 8:
                monthName = "August";
                break;
            case 9:
                monthName = "September";
                break;
            case 10:
                monthName = "October";
                break;
            case 11:
                monthName = "November";
                break;
            case 12:
                monthName = "December";
                break;
            default:
                monthName = "Invalid input! Please enter a number between 1 and 12.";
                break;
        }

        System.out.println("对应的英文月份是: " + monthName);
    }
}

在这个例子中，我们使用了`switch`语句来根据输入的月份数字匹配相应的英文名称。如果输入超出范围，会给出错误提示。
