Question

i hv 4 columns in a DB: first_count,second_count,3rd_count and level.
i hv to find the max between the three counts & depending on the count,the level is updated. If first_count is the max,the level is 1, if the 2nd_count is the max,level is updated to 2 else it has to set level=3.
int 1st= retrieve_1st();
int 2nd=retrieve_2nd();
int 3rd=retrieve_3rd();
max_count(1st,2nd, 3rd);
int retrieve_1st()
     int ret=0;
     try {
     statement = connection.createStatement();
     ResultSet r= statement.executeQuery("select first_count from User");
     boolean success=r.next();
     if (success==true)
     ret=r.getInt("first_count");
statement.close();}
     else
     System.out.println("Error with retrieve");
     }//try
     catch ( Exception ex )
          ex.printStackTrace();
     }//catch
return ret;
public void max_count( int 1st, int 2nd, int 3rd)
     int max= 1st;
     if (2nd> max)
     max= 2nd;
     else if (3rd> max)
max= 3rd;
if ( max==(1st))
     int lvl=1;
     set_level(lvl);
}//if
else if ( max==(2nd))
int lvl=2;
set_level(lvl);
}//else if
else if ( max==(3rd))
int lvl=3;
set_level(lvl);
}//else if
}//end of function max_count
public void set_level(int lvl)
int i=0;
try {
statement = connection.createStatement();
ResultSet r= statement.executeQuery("select level from User");
     boolean success=r.next();
if (success==true)
i=r.getInt("inter_count");
statement.executeUpdate("UPDATE User SET level="+lvl);
statement.close();}
else
     System.out.println("Error with set_level");
}//try
catch ( Exception ex )
ex.printStackTrace();
}//catch
}//end function set_level
