java中截取未知长度字符串主要是使用String类，示例如下：
/*** @author cn
* @param s 要截取的字符串
* @param length 要截取字符串的长度->是字节一个汉字2个字节
* return 返回length长度的字符串（含汉字）
*/
private static String getTitleToTen(String s, int length) throws Exception
{
byte[] bytes = s.getBytes("Unicode")
int n = 0
int i = 2
for ( i < bytes.length && n < length i++){
if (i % 2 == 0){
n++
}else{
if (bytes[i] != 0){
n++
}
}
}
/*if (i % 2 == 1){
if (bytes[i - 1] == 0)
i = i - 1
else
i = i + 1
}*/
//将截一半的汉字要保留
if (i % 2 == 1){
i = i + 1
}
String eside = "................................................................."
byte[] byteEside = eside.getBytes("Unicode")
String title = ""
if (bytes[i-1] == 0){
title = new String(bytes, 0, i, "Unicode")+new String(byteEside,0,40,"Unicode")
}else{
title = new String(bytes, 0, i, "Unicode")+new String(byteEside,0,38,"Unicode")
}
return title
}
