返回值的问题````````
public int symbol(String bit)
{
int result=0;
String anotherString=null;
int bitlength=0;
String S =bit;
boolean b = Pattern.matches( "[a-zA-Z0-9]* ",S);
try{anotherString = new String(S.getBytes( "GBK "), "ISO8859_1 ");}catch(Exception e){}
bitlength=(int)anotherString.length();
return bitlength;
}
报这个错误

怎么把bitlength的值返回出来````
------解决方案--------------------bitlength=(int)anotherString.length();
return bitlength;
这个应该没问题吧,手头没环境,我觉得也没必要cast

-----------------------
不能把int转换成String,自己找找
------解决方案--------------------运行了下没报错
------解决方案--------------------STRING类型的.length()本身就是返回一个INT类型.没有必要在加上(INT)吧.
如果是TRY块中anotherString出现赋值错误的话.不知道下边进行求长度会出错还是。
