I dont understand how to get in methods in my class in JAVA

Question

I don't understand why I get a compilation error, I hope someone can help out here. I would appreciate it a lot. I'm trying to make a system for a lot of cars.

public class Car {
    //Instance Variables
    String make;
    String model;
    int year;
    boolean isNew;
    double miles;
    String owner;
    public void sell (String newOwner) {
        owner=newOwner;
        if (isNew){
            isNew=false;
        }
    }
    public boolean isOld() {
        int thisYear=Calendar.getInstance().get(Calendar.YEAR);
        if (thisYear-year > 10) {
            return true;
        } else {
            return false;
        }
    } 
}
public static void main(String[] args) {
    Car myCar = new Car(); //myCar is a variable and new the keyword
    myCar.make = "Audi";
    myCar.model = "A4";
    myCar.year =2014;
    myCar.isNew=true;
    myCar.miles =0;
    myCar.owner ="Jeyson";
    boolean isMyCarOld = myCar.isOld();
    myCar.sell("John Doe");
    System.out.println("Car owned by" + myCar.owner);
}

it seems that the main methos is outside your class and this is not correct :) — Youcef LAIDANI, Jun 19 '17 at 10:09
just replace the last `}` before the main method and put is after the `}` of the main methos `}}` — Youcef LAIDANI, Jun 19 '17 at 10:11
If you indented your code properly it would be clear where the errors were. — khelwood, Jun 19 '17 at 10:13

You cannot write main method out side of your class. It should be written inside class.

The following code should work,

public class Car {
    //Instance Variables
    String make;
    String model;
    int year;
    boolean isNew;
    double miles;
    String owner;
    public void sell (String newOwner) {
        owner=newOwner;
        if (isNew){
            isNew=false;
        }
    }
    public boolean isOld() {
        int thisYear=Calendar.getInstance().get(Calendar.YEAR);
        if (thisYear-year > 10){
            return true;
        } else {
            return false;
        }
    }
    public static void main(String[] args){
        Car myCar = new Car(); //myCar is a variable and new the keyword
        myCar.make = "Audi";
        myCar.model = "A4";
        myCar.year =2014;
        myCar.isNew=true;
        myCar.miles =0;
        myCar.owner ="Jeyson";
        boolean isMyCarOld = myCar.isOld();
        myCar.sell("John Doe");
        System.out.println("Car owned by" + myCar.owner);
    }
}
