你沒有讀取輸入的代碼。

我用了Scanner sc = new Scanner(System.in); int nextInt = sc.nextInt();還是不行，能根據(jù)代碼講解的詳細(xì)點(diǎn)？

為什么用else if 輸出就不對了 import java.util.Scanner; public class WhatDay { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("請輸入數(shù)字1-7："); int nextInt = sc.nextInt(); if (nextInt == 1) { System.out.println("星期一"); } else if (nextInt == 2) { System.out.println("星期二"); } else if (nextInt == 3) { System.out.println("星期三"); } else if (nextInt == 4) { System.out.println("星期四"); } else if (nextInt == 5) { System.out.println("星期五"); } else if (nextInt == 6) { System.out.println("星期六"); } else if (nextInt == 7) { System.out.println("星期日"); } } }
