如何将 int 与字符串数组进行比较？

Question

我试图将 int 的用户输入与 String 数组进行比较。

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();

    }

}

Answer 1

只需使用 input 作为索引，假设他们输入 1 为一月，那么您可以调用索引：System.out.println("You've selected the month of: " + month[number]);将为 输出“一月”，当然month[number]，您还必须检查是否超出范围。

Answer 2

试试这个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]);答：请输入一个 0 到 13 之间的数字13请输入 0 到 13 之间的数字12来自用户 12 的输入与月份匹配：十二月
