編寫一個簡單的循環

Question

嘿所以我正在編寫一個程序，用戶輸入正好10個單詞，並且計算機輸出每個單詞中有一個A或a。我用一些幫助編寫了該程序，現在我需要現在如何讓用戶可以通過一個while循環重新輸入10個單詞。這是我到目前爲止。

import java.util.Scanner; 

public class ReadASH{ 
    public static void main(String[] args){ 
     Scanner in = new Scanner(System.in); 

     String name; 
     String S=""; 
     System.out.println("Please enter any word."); 
     S = in.nextLine(); 
     if(S.contains("a")||S.contains("A")) 
      System.out.println(S); 
     else System.out.println("The word you entered contains no a's or A's"); 
    } 
}

實際上你需要有一個循環，是這樣的：根據評論

import java.util.Scanner; 

public class ReadASH{ 
    public static void main(String[] args){ 
    Scanner in = new Scanner(System.in); 

    String name; 
    String S; 
    for (int i=0; i<10; i++) { 
     System.out.println("Please enter any word."); 
     S = in.nextLine(); 
     if (S.contains("a")||S.contains("A")) 
     System.out.println(S); 
     else System.out.println("The word you entered contains no a's or A's"); 
    } 
    } 
} 

更新代碼：

import java.util.Scanner; 

public class ReadASH{ 
    public static void main(String[] args){ 
    Scanner in = new Scanner(System.in); 

    String name; 
    int wordsToRead = 10; 
    String words[] = new String[wordsToRead]; 

    for (int i=0; i< wordsToRead; i++) { 
     System.out.println("Please enter any word."); 
     words[i] = in.nextLine(); 
    } 
    for (int i=0; i< wordsToRead; i++) { 
     if (words[i].contains("a")||words[i].contains("A")) 
     System.out.println(words[i]); 
    } 
    } 
}
