檢查字符串是否包含陣列中的任何字母 - JAVA

Question

String [] V = {"a","e","i","o","u"}; 

    Scanner input = new Scanner(System.in); 
    String A; 
    System.out.println("Enter any letters"); 
    A=input.next(); 

    if(A.contains(V)) { 
     System.out.println("success"); 
    } 

底線。如果有在「V」串的字母是「A」我希望它繼續以「成功」

Answer 1

嘗試使用foreach循環是這樣的：

 for (String string : V) { 

      if(A.contains(string)) { 
       System.out.println("success"); 
      } 
     } 

因爲在方法contains(CharSequence)類型字符串不適用於參數（String []）。

它工作作出一些改變你的代碼

String [] V = {"a","e","i","o","u"}; 
    boolean flag = false; 

    Scanner input = new Scanner(System.in); 
    String A; 
    System.out.println("Enter any letters"); 
    A=input.next(); 

    for(String temp:V) 
    { 
     if (A.contains(temp)) { 
      flag = true; 
      break; 
     } 
    } 

    if(flag) 
     System.out.println("Success"); 
    else 
     System.out.println("Not Success");
