JAVA字符串的反转和比较

字符串的反转（1）用String的toCharArray方法把String转换为char数组，再对数组进行排序                int m = s.length();char temp;char[] cs = s.toCharArray();for(int i =0; i<m/2; i++){temp=cs[i];cs[i]=cs[m-1-i];cs[m-1-i]=temp;}String str = new String(cs);（2）用StringBuilder的reverse方法                StringBuilder sb = new StringBuilder(s);sb.reverse();字符串的排序 （1）用compareTo来比较两个字符串（2）用Arrays.sort()对String数组排序<script type="text/javascript"><!--
