    Default Will someone help me with code? Creating classes, getters & setters. Beginner :(

    package CarLot;

    Main Method:


    //HW06.java CS 140-01
    //10/23/12
    //Dominic Torro
    //This program builds several car objects


    public class CarLot
    {

    public static void main (String[] args)

    {

    //Builds 3 car objects.

    Car car1 = new Car (1996, "Dodge", "Neon", "4dr", "rust" );
    Car car2 = new Car (1978, "Ford", "Mustang", "2dr", "black");
    Car car3 = new Car (1967, "Chevrolet", "Corvette", "2dr", "silver");

    //Header to explain what program does

    System.out.println("This program builds several car objects");

    //Print original information for each car using a toString()

    System.out.println ("Car 1: " +car1);
    System.out.println ("Car 2: " +car2);
    System.out.println ("Car 3: " +car3);

    //Set color of car3 to red
    car3.setColor("red");

    //Set year of car1 to 2001
    car1.setYear(2001);

    //Set model of car 1 to Challenger
    car1.setModel("Challenger");

    //Set model of car2 to Taurus
    car2.setModel("Taurus");

    //Print new info for car1 using getter methods
    System.out.println("Car 1 is now a: " +car1.getYear() +car1.getModel());

    System.out.println ("Car 2 is now a: " +car2.getModel());

    System.out.println ("Car 3 is now a: " +car3.getColor());
    }
    }

    This is my worker class:

    package CarLot;

    import java.text.DecimalFormat;

    public class CarWorker
    {
    //Instance Data
    int year;
    String make;
    String model;
    String bodytype;
    String color;

    //Constructor method

    public Car (int yearIn, String makeIn, String modelIn, String bodytypeIn, String colorIn)


    {
    year = yearIn;
    make = makeIn;
    model = modelIn;
    bodytype = bodytypeIn;
    color = colorIn;
    }

    //Getters and setters

    public int getYear()

    {
    return year;
    }

    public void setyear(yearIn)

    {
    year = yearIn;
    }

    public String getmake()

    {
    return make;
    }

    public void setmake(makeIn)

    {
    make = makeIn;
    }

    public String getmodel()

    {
    return model;
    }

    public void setmodel(modelIn)

    {
    model = modelIn;
    }

    public String bodytype()

    {
    return bodytype;
    }

    public void setbodytype(bodytypeIn)

    {
    bodytype = bodytypeIn;

    }

    public String getcolor()

    {
    return color;
    }

    public void setcolor(colorIn)

    {
    color = colorIn;
    }

    public String toString()
    {

    String result = "";
    return result = ""
    }
    }

    firstly, the carWorker class, the constructor MUST be the same name as the class, you wrote public car(int....)
    it needs to be carWorker(int....)
    secondly, the toString method in the same class should return a string,
    you wrote return result = "";
    which is actually a boolean query that returns true or false, not a string.
    what you can do is build the result variable as following:
    String result = "";
    result = result + getColor() + " , " + getModel() + .....
    return result;
    hope it helps,
    btw if you are using ecliple or netbeans or something like that you can read exactly which errors you get and understand from
    that where the problem is.

    secondly, the toString method in the same class should return a string,
    There is nothing wrong with:
    return result = "";
    ...assuming you want to return the empty string.

    Please see the announcements page for the use of code tags.

    Your code? Are you sure that it's not your task to find and correct the errors in the code? :-)
