I am using some exceptions, but even if one is thrown and catched, it does continue output whats after the catch block.

I want my exception that is thrown, to get catched and only print out whats in the catch body, unless there is no exception and move on to the last souf.

Somehow though, when i have an exception, my catch body is printed but also the souf after it, that should not be printed.

How do i organize these exceptions?

------- a method that throws an exception

   public double getHeight() throws ExceptionCheck {

        //if end point is not set, return -1 (error)

        if(points[1] == null){

            throw new ExceptionCheck("The height cannot be calculated, the end point is missing!nn");

        } else {

            double height = points[1].getY() - points[0].getY();

            return height;

        }

    }

------- the method that handles the throw from getHeight

@Override

public double getArea() {

    //if end point is not set, return -1 (error)



    double area = 0;



    try {

        area = getHeight() * getWidth();

    }

    catch(ExceptionCheck e){

        System.out.printf("The area cannot be calculated, the end point is missing!nn");

    }



    return area;

}

---------- here the last SOUF after the catch should not be printed, but gets printed anyways

private static void printArea(Shape shape) {

    System.out.println("Printing area of a " + shape.getClass().getSimpleName());



    double area = 0d;

    // Get area of the shape and print it.

    try {

        area = shape.getArea();

    }

    catch(ExceptionCheck e){

        System.out.printf(e.getMessage());

    }

   System.out.println("The area is: " + area);

}

That isn't how catch works. If that shouldn't be printed when there is an exception, you must move it into the body of the try. Like,

// Get area of the shape and print it.

try {

    double area = shape.getArea();

    System.out.println("The area is: " + area); // <-- if the previous line throws

                                                // an exception, this will not print.

}

catch(ExceptionCheck e){

    System.out.printf(e.getMessage());

}

Your method getArea doesn't actually throw the Exception. It prints and swallows it. For the above catch to be invoked, you would also have to modify getArea like

@Override

public double getArea() throws ExceptionCheck {

    try {

        return getHeight() * getWidth();

    }

    catch(ExceptionCheck e){

        System.out.printf("The area cannot be calculated, the end point is missing!nn");

        throw e; // <-- add this.

    }

}
