Iterating through SQL results in Java -


i working on project based on simple sql database. need happen have end-user prompted enter warehouse pull list of trucks database , present trucks 1 @ time user can input current mileage. have warehouse input working fine , able retrieve truck list input well. can't find way present 1 @ time current mileage input. below code have far:

public class preventativemaintenance {  public static void main(string[] args) throws exception  {     scanner kb = new scanner (system.in);     system.out.print("warehouse? ");      class.forname("com.mysql.jdbc.driver");     connection con = (connection) drivermanager.getconnection("jdbc:mysql://localhost:3306/test", "root", "");      string warehouse = kb.next();      string query = "select * `new_schema`.`trucks` `warehouse` = '" + warehouse + "'";      statement st = con.createstatement();       resultset rs = st.executequery(query);   } }

i have attempted use arraylist of objects called truck , built objects sql query. however, ran same issue cannot find way present different truck numbers 1 @ time user may input current mileage.

you can try this: 

    //once resultset rs after executing query     while(rs.next()){           string truckname = rs.getstring("<name of truck column>");         settruckmileage(truckname);     }      private void settruckmileage(string truckname){           scanner kb = new scanner (system.in);         system.out.print("enter mileage truck " + truckname +" : ");          integer mileage = kb.nextint();          //save mileage entered user     }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
