help with methods return types

[Eric Johns]

I have car class

public Car( String inputMake,String inputModel,String inputType, double inputPrice, double inputSafetyRating, int inputMpg)
{
make=inputMake;
model=inputModel;
type=inputType;
suggestedRetailPrice=inputPrice;
safetyRating=inputSafetyRating;
milesPerGallon=inputMpg;  

and a method

 
public ?? printCarDetails(double totalFit,String userCarType)
 {
 boolean findFit;
 
 if  ((totalFit >=80) && (userCarType.compareTo(type)==0))
 {
    
 findFit=true;
 "need to return this values"
                System.out.println("Make: "+ carMake);
System.out.println("Model: "+ carModel);
System.out.println("Type: "+ carType);    
       System.out.println("Retail Price: "+ carRetailPrice);
       System.out.println("Safety Rating: "+ carSafetyRating);
       System.out.println("Miles Per Gallon: "+ carMilesPerGallon);
        System.out.println("Fit: "+ fitWeight)
   
 }
 else findFit=false;
 return findFit;
 } 

in that methods I need to return those values,in program that will be calling on that method and it's findingmatchingcar class with it's with 80% or greater of the users required inputs my question is I'm having program with the return types and how would I return those values and have them get printed? thanks Eric

I am eager to help, but what is the question, again?

My basic question is I have to return make,model,type,price,safetyrating,mpg if that car is with in my users preference but how do you return values with different types, their are strings,int,doubles.

If you are using different types you could always use the wrapper classes and change them about as you feel fit.
for example

String a = new String("1234")
//convert the string to an int
int b = new Integer(a).intValue();
//or you can do this
int b = Integer.parseInt(a);
//alternately you can convert numeric data to string
double d = 25.50;
String s = new Double(d).toString();

this would turn the String "1234" into the int 1234.
the second part would turn the double 25.50 into the String "25.50"
hope this helps.

You can always return an object that contains all the needed info.

since 'findfit' is a bool, make the method type bool but put the

 return findFit; 

after the

 System.out.println("Make: "+ carMake);
System.out.println("Model: "+ carModel);
System.out.println("Type: "+ carType);
System.out.println("Retail Price: "+ carRetailPrice);
System.out.println("Safety Rating: "+ carSafetyRating);
System.out.println("Miles Per Gallon: "+ carMilesPerGallon);
System.out.println("Fit: "+ fitWeight)

so it would look something like

  
public [B]bool[/B] printCarDetails(double totalFit,String userCarType) 
{
     boolean findFit;  
     if  ((totalFit >=80) && (userCarType.compareTo(type)==0)) 
     {
         findFit=true; 
         System.out.println("Make: "+ carMake);
         System.out.println("Model: "+ carModel);
         System.out.println("Type: "+ carType);
         System.out.println("Retail Price: "+ carRetailPrice);
         System.out.println("Safety Rating: "+ carSafetyRating);
         System.out.println("Miles Per Gallon: "+ carMilesPerGallon);
         System.out.println("Fit: "+ fitWeight);
         [B] return findFit; [/B]
     }
     else 
        findFit=false;
     return findFit; 
} 

is this what your trying to do?
then you wouldnt be assigning findFit to anything, you would be using it in an if statement, like

if(printCarDetails());

or if all your trying to do is Print the details if it fits, make it like this

  
public [B]void[/B] printCarDetails(double totalFit,String userCarType) 
{
     if  ((totalFit >=80) && (userCarType.compareTo(type)==0))
     {
         System.out.println("Make: "+ carMake);
         System.out.println("Model: "+ carModel);
         System.out.println("Type: "+ carType);
         System.out.println("Retail Price: "+ carRetailPrice);
         System.out.println("Safety Rating: "+ carSafetyRating);
         System.out.println("Miles Per Gallon: "+ carMilesPerGallon);
         System.out.println("Fit: "+ fitWeight);
     }
     else 
     {
          System.out.println("Car does not match Specs");
     }
} 

Then all you would be doing is displaying the information if it was the right car or else display that its not a match. hope this helps.
