string str = "(select name from sysparameter where category='2' and code=nation) as nation"
现在只需要as后面的"nation"这一个单词前面的都不要，如何解决望高人指点。

public class YunNian {
public static void main(String[] args) {
String str = "(select name from sysparameter where category='2' and code=nation) as nation";
int i = str.lastIndexOf("as");

String s = str.substring(i + 3);
System.out.println(s);
}
}

String str = "(select name from sysparameter where category='2' and code=nation) as nation";
System.out.println(str.substring(str.indexOf("as ") + 3));

str.substring(str.indexOf("as"),str.length())
