    CODEclass AreaRectangle {
    double x;
    double y;

    AreaRectangle() {
    this.x = 4;
    this.y = 2.3;
    }

    void calAreaRectangle() {
    double a = this.x * this.y;
    double b = 0;
    System.out.print("The area of the Rectangle is " + a + ". It's length is " + this.x + ". It's breadth is " + b);
    }
    }

    public class Main {
    public static void main(String args[]) {
    AreaRectangle A = new AreaRectangle();
    A.calAreaRectangle();
    }
    }

    You forgot a } on the end.

    That's why you should format the code, like above.

    And also:
    • b wasn't defined
    • "main(String args[])" doesn't seem suitable in the AreaRectangle class.
    Also the poster should consider using a IDE for help with detecting these errors and formatting the code better, may I suggest NetBeans.
