public class Circle {

    private double radius; // an instance variable

    public Circle(double radius){
        this.radius = radius; // the instance variable is assigned the value
                              // passed by the method parameter
    }

    public double getArea(){
        return radius * radius * Math.PI;
    }
}

Recall that after the initial declaration, you should first define your instance variables, then write your constructor and finally define your instance methods.
