变数字：str.charAt(0) - 'a' + 1import java.util.Arrays; import java.util.Collections; import java.util.List; public class Test6 { public static void main(String[] args) { /*  * 把下面的String[] s={"a","b","c","d","e","f"};  *   * 变成int[]s={1,2,3,4,5,6};  */ String[] s = { "a", "b", "c", "d", "e", "f" }; List<String> list = Arrays.asList(s); Collections.reverse(list); list.toArray(s); for (String str : s) { System.out.print((str.charAt(0) - 'a' + 1) + " "); } } }
