如何讀取字符串中的字符並根據輸入返回？

Question

這就是我所要做的：我想製作一個程序，要求用戶輸入：你的名字。

這是我需要幫助的：然後，我希望程序讀取名稱中的每個字符，字母。最後，我想讓它返回與用戶名中每個字符對應的形容詞列表。

這是我到目前爲止有：

public static void main (String [] args) { 

    System.out.println("This program will give meanings to every " 
         + "letter in your name.\n"); 

    Scanner input = new Scanner (System.in); 
    System.out.println("Please enter your name:"); 
    String name = input.next(); 

    String A = "adventurous"; 
    String B = "bold"; 
    String C = "caring"; 
    String D = "devoted"; 
    String E = "encouraging"; 
    String F = "funny"; 
    String G = "gentle"; 
    String H = "honest"; 
    String I = "intelligent"; 
    String J = "joyful"; 
    String K = "kind"; 
    String L = "loving"; 
    String M = "mature"; 
    String N = "neat"; 
    String O = "organized"; 
    String P = "persistent"; 
    String Q = "quick"; 
    String R = "religious"; 
    String S = "sensitive"; 
    String T = "thankful"; 
    String U = "useful"; 
    String V = "virtuous"; 
    String W = "witty"; 
    String X = "this letter isn't in your name"; 
    String Y = "young"; 
    String Z = "zany"; 
}

把你的形容詞在地圖（對於char關鍵和形容詞的值），而不是使用這些字符串，則名轉換爲CharArray，遍歷它併爲每個字母從Map中獲取項目。您可以將您的形容詞放入列表中，然後再打印出來。

//create the map and the list of adjectives 
Map<Character, String> adjectives = new HashMap<>(); 
List<String> personAdjectives = new ArrayList<>(); 
//fill the map (although it would be better retrieving data from a database) 
adjectives.put('a',"adventurous"); 
adjectives.put('b',"bold"); 
// ... 
//convert the name to a char array 
char[] chars = name.toCharArray(); 
//iterate over it 
for(char c : chars){ 
    //access the map and fill the list 
    personAdjectives.add(adjectives.get(c)); 
} 
//print the list
