Create a public class called Exceptioner that provides one static method exceptionable. exceptionable accepts a single int as a parameter. You should assert that the int is between 0 and 3, inclusive.
If the int is 0, you should return an IllegalStateException. If it's 1, you should return a NullPointerException. If it's 2, you should return a ArithmeticException. And if it's 3, you should return a IllegalArgumentException.

Answer:

// Begin class declaration

public class Exceptioner {

   

   // Define the exceptionable method

   public static void exceptionable(int number){

      //check if number is 0.

       if(number == 0) {

           //if it is 0, return an IllegalStateException

           throw new IllegalStateException("number is 0");

       }

      //check if number is 1        

       else if(number == 1) {

           //if it is 1, return a NullPointerException

           throw new NullPointerException("number is 1");

       }

      //check if number is 2        

       else if(number == 2) {

           //if it is 2, return an ArithmeticException

           throw new ArithmeticException("number is 2");

       }

       

      //check if number is 3

       else if(number == 3) {

           //if it is 3, return an IllegalArgumentException

           throw new IllegalArgumentException("number is 3");

       }

   }

}

Sample Output:

Exception in thread "main" java.lang.ArithmeticException: number is 2                                                                          

       at Main.exceptionable(Main.java:26)                                                                                                    

       at Main.main(Main.java:36)  

Explanation:

The code is written in Java with comments explaining important parts of the code.

A sample output for the call of the method with number 2 is also provided. i.e

exception(2)

gives the output provided above.
