That may be overkill. Here all you're doing is a little logic exercise and will likely be returning just a String to the user (unless this is part of a bigger program).

Also, you may wish to choose better subject headings for your post here. Think of your subject heading as a headline for your post, something that will tell folks here in one line what to expect in the post. Very vague or overly general headings often get ignored while specific and informative headings often get the attention of someone who is an expert in this problem. Just a suggestion, YMMV.

Depends on the design. A lot of apps have defaults. Some don't.
what would your user prefer?

nvm about that but how bout this

public class VehicleChooser
{
public static void main(String args[])
{
// Declare and initialize variables here.
String passengerString;
String mileageString;
String cargoString;
int passengerCar;
int mileageCar;
int cargoSpace;
System.out.println("Welcome to the Front Range Vehicle Center!");
String passengerString = JOptionPane.showInputDialog("How many passenger at most will you need to carry(1-8)?");
String mileageString = JOptionPane.showInputDialog("How important is mileage ?(On scale 1-10)?");
String cargoString = JOptionPane.showInputDialog("How important is cargo space(On scale 1-10)?");
passengerCar = Integer.parseInt(passengerString);
mileageCar = Integer.parseInt(mileageString);
cargoSpace = Integer.parseInt(cargoString);
if ( passengerCar>=9 || passengerCar<=0)
System.out.println( "Sorry but that is invalid passenger count");
else if ( passengerCar>=6)
System.out.println( "Based on your inputs, please consider our fine Sports Utility Vehicle. ");
else if ( mileageCar>=cargoSpace)
System.out.println( "Based on your inputs, please consider our fine Hybrid Sedan.");
else if ( passengerCar==5)
System.out.println( "Based on your inputs, please consider our fine Sports Utility Vehicle. ");
else if ( cargoSpace >=7)
System.out.println( "Based on your inputs, please consider our fine Pickup w/Cab.");
else if ( cargoSpace>10 || cargoSpace<1)
System.out.println( "Sorry but that is invalid Cargo Space Rating!");
else if ( mileageCar>10 || mileageCar<1)
System.out.println( "Sorry but that is invalid mileage rating!");
else
System.out.println( "Based on your inputs, please consider our fine Sports Utility Vehicle. ");
System.out.println("Thanks for stopping by, come again soon.");


System.exit(0);
}
}

this is what it said when i compile it

ing[])

assenger at most will you need to carry(1-8)?");

A variable can be declared only once in the same scope.

Do you know what "defined" means?

int anInt; // define a variable of type int named anInt

A definition has the type before the variable name. Here the type is int.
