怎么错了？
public String StrLength(String str,int StrLong){
int a = str.length();
if(a > 8){
str = str.substr(0,StrLong);
return str;
}
else
return str;
}
怎么错了？
500 Servlet Exception
C:\resin\doc\WEB-INF\classes\mebeans\DisposeString.java:70: Method Substr(int, int) not found in class java.lang.String.
str = str.Substr(0,6);

没有Substr()方法，是substring(String k,int i)

String没有substr功能呀
public static final String left(String s,int ii)
{String ss="";
int n = s.length();
int j=1;
for (int i = 0 ;i<n;i++)
{ if (i>ii-1) {break;}
char c =s.charAt(i);
ss=ss+c;
}
return ss;}

int j=1;
for (int i = 0 ;i<n;i++)
{ if (i>ii-1) {break;}
char c =s.charAt(i);
ss=ss+c;
