如何在String数组中获取char的索引位置

Question

如何在数组c中获取char chars的索引位置？。

public static final String[] chars = new String[]{"A","B","C","D","E","F"};
String c = "E";

// the answer is 4.

Answer 1

如果您的数组已排序，则可以使用

  

Arrays.binarySearch（）

int answer = Arrays.binarySearch(chars, c);
return answer;

如上所述。否则使用for循环。

for (int i=0; i<chars.length; ++i) {
   if (s[i].equals(c)) {
        return i;
   }
}

这是解决方案，希望这可以帮助你

    String[] src = new String[]{"A","B","C","D","E","F"};
    int biggerWher = Arrays.asList(src).indexOf("E");
    System.out.println(biggerWher);
