字符串操作技巧

1、递归实现字符串倒序

public static String reverse(String originStr) {   if(originStr == null || originStr.length() <= 1)             return originStr;    return reverse(originStr.substring(1)) + originStr.charAt(0);    }

2、字符串转码

String s1 = "你好";String s2 = new String(s1.getBytes("GB2312"), "ISO-8859-1");
