Jun 14, 2024 · The program below defines a new circle class named CircleWithException, which is the same as CircleWithPrivateDataFields except that the setRadius(double newRadius) method throws an IllegalArgumentException if the argument newRadius is negative.

CircleWithException c1 = new CircleWithException(5); //It's OK CircleWithException c2 = new CircleWithException(-5); // Here, there is an exception, so it doesn't complete try block and move to catch the exception

CircleWithException c1 = new CircleWithException(5); CircleWithException c2 = new CircleWithException(-5); CircleWithException c3 = new CircleWithException(10);

The test program creates three CircleWithException objects, c1 , c2 , and c3 , to test how to handle exceptions. Invoking new CircleWithException(-5) (line 6 in Listing 17.5) causes the setRadius method to be invoked, which throws an IllegalArgumentException , because the …

In CircleWithException, you have to declare the variables and methods to fulfill the bellowing functionalities. 1. Design the method to set the radius of the circle. Here’s the best way to solve it.

CircleWithException c2 = new CircleWithException(-5); CircleWithException c3 = new CircleWithException(0); catch (IllegalArgumentException ex) { System.out.println(ex); System.out.println("Number of objects created: " +. CircleWithException.getNumberOfObjects());

CircleWithException c1 = new CircleWithException (5); CircleWithException c2 = new CircleWithException (-5); CircleWithException c3 = new CircleWithException (0); catch (IllegalArgumentException ex){ System.out.println(ex); System.out.println("Number of objects created: "+CircleWithException .getNumberOfObjects()); can anyone help me?
