java - How to fix Error: Unresolved compilation problems: Syntax error on token "rs" -

can please tell me compilation error

"exception in thread "main" java.lang.error: unresolved compilation problems: syntax error on token "rs", delete token method getstring(int) undefined type string @ selecttest.main"

in below java code

//selecttest.java import java.sql.*; public class selecttest1 {     public static void main(string args[])throws exception     {         class.forname("sun.jdbc.odbc.jdbcodbcdriver");         connection con = drivermanager.getconnection("jdbc:odbc:oradsn","system","123");         statement st = con.createstatement();         resultset rs = st.executequery("select*from student");         {             while(rs.next())             {                 system.out.println(rs.getint(1)+" "+rs.getstring(2)+" "rs.getstring(3));             }             rs.close();             st.close();             con.close();         }     } } 

the last rs.getstring(3) forget '+'

system.out.println(rs.getint(1)+" "+rs.getstring(2)+" " +rs.getstring(3));
