Students have asked these similar questions
create a method:
public static double division(double a, double b) throws IllegalArgumentException { }
that divides a/b and returns the division value. if b == 0 it throw the IllegalArgumentException since anything divided by O is an Illegal division operations. Complete the logic for this method.
2. Call you method in an application (main() method) be sure to include a try and catchf block, where the try {} block contains the method division that can possible throw an exception, and the following catchf} block(s) to handle the possible Exceptions.
In Java when a method throws a checked Exception, what must we always do when calling that method?
A. Make sure to declare the method as static.
B. Put it inside a try/catch block.
C. Set the permission level of the method to private.
D. Check our input, and if it will be bad input we must throw an exception before calling the method.
We are asked to add an exception to the game. Please see below.
For this part of the assignment you can start by creating your own exception in a file named NumberGuesserIllegalStateException.java, with this code:
public class NumberGuesserIllegalStateException extends Exception {
public NumberGuesserIllegalStateException(String errorMessage) {
super(errorMessage);
}
}
Next modify your code so that the higher and lower methods of both the NumberGuesser and RandomNumberGuesser should throw the exception if there are no more remaining numbers to guess. You might be able to achieve this by adding the logic to your NumberGuesser and letting RandomNumberGuesser inherit the behavior. Or you might need to add the logic to both classes. It will depend on your implementation.
Finally add a try-catch block to your number guessing game so that the user is notified if the user cheats.

- Write a method that will take in a time in 24 hour format (1430) and return the time in 12 hour format (2:30pm). This method should have appropriate exception handling. If an incorrect time is sent as an argument (something out of bounds or 23(#4k in other words garbage), then your method should throw a TimeFormatException which you define. In no case should your method throw an unhandled exception! Show how to test the method to be sure.arrow_forwardQ# When JUnit testing with exceptions, which of the following is true? Group of answer choices A successful test happens whenever an exception is not thrown. Exceptions and tests should not be used together. A failed test results when you catch an exception on valid input. If you give an illegal argument to a method the JUnit test will fail. Q# When you want a method to return nothing, what do you put for the return type? Group of answer choices boolean false void null Q# Which of the following statements are true? Group of answer choices All of the options are true. Methods can take multiple primitives as arguments. Methods can take objects of other classes as arguments. A method for a class can take an object of that class as an argument. Q# What does Java guarantee is part of every class?
