如何在字符串中存儲用戶輸入？

Question

如何將用戶鍵盤輸入中的每個答案存儲在字符串中？

for (int i = 0; i < 3; i++){ 
    System.out.println("insert the answer "); 
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); 

    String userAnswer[] = new String[3]; 

    try { 
     userAnswer[i] = br.readLine(); 
    } catch (IOException ioe) { 
     System.out.println("IO error ,trying to read your answer"); 
     System.exit(1); 
    } 
    int count =0; 
    count++; 
    String we[] = new String[3]; 

    System.out.println("the answer is " + userAnswer); 
    System.out.println("the answer is " + count); 
} 

Answer 1

使用Scanner。

Scanner scanner = new Scanner(System.in); 
List<String> answers = new ArrayList<String>(); 
for(int i = 0; i < 3; i++) 
{ 
    answers.add(scanner.nextLine()); 
}
