一数组 {'f','F','K','A','a','j','z'} 要求排序 为 {'A','a','F','f','j','K','z'} 发个个人认为比较好的方案
java code import java.util.Arrays; import java.util.Comparator; public class SortTest { public static void main(String args[]) { char [] chs = { ' f ' , ' F ' , ' K ' , ' A ' , ' a ' , ' j ' , ' z ' }; chs = sortChars(chs, false ); for ( char c: chs) { System.out.println(c); } } /** * 对给定的字符数组进行字典排序 * @param chs 目标字符数组 * @param upperFisrt 大写字母是否在前 * @return 排序后的字符数组 */ public static char [] sortChars( char [] chs, final boolean upperFisrt) { Character[] srcArray = new Character[chs.length]; char [] retArray = new char [chs.length]; int index = 0 ; for ( char ch: chs) { srcArray[index ++ ] = ch; } Arrays.sort(srcArray, new Comparator < Character > () { public int compare(Character c1, Character c2) { char ch1 = Character.toUpperCase(c1); char ch2 = Character.toUpperCase(c2); if (ch1 == ch2) { int tempRet = c1.charValue() - c2.charValue(); return upperFisrt ? tempRet: - tempRet; } else { return ch1 - ch2; } } }); index = 0 ; for ( char ch: srcArray) { retArray[index ++ ] = ch; } return retArray; } }
