- 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.Please explain what each line of code does by providing comments. Java Intellij Project. Choose any program from this semester that accesses a file, but that does not use try-catch blocks to handle file not found exceptions. The program may be one you wrote or a sample provided by your instructor. Add a try and catch block to take the exception. You can decide what the handler does. It could simply print a message – such as on the screen in the IDE or a JOptionPane error message dialog box – or it could allow the user to enter the correct file name. Add comments to the beginning of the project code describing what you did and how it works.In Java, what is the difference between a checked exception and an unchecked exception? A. A checked exception is one that is handled in a try-catch block. An unchecked exception is one that is declared via the throws keyword in the method signature B. An unchecked exception is an exception like a NullPointerException which we do not anticipate. However, exceptions we can anticipate, like NumberFormatException when using Integer.parselnt, are checked Exceptions C. An unchecked exception is one that is handled in a try-catch block. A checked exception is one that is declared via the throws keyword in the method signature D. Java syntactically forces you to handle checked exceptions, or use throws to declare the function is capable of throwing a checked exception Reset Selection
- In Java, please comment and comment with output please This programming assignment involves learning about some of the common exceptions that occur in Java programs. Consider the following exception types: NullPointerException ArrayIndexOutOfBoundsException ClassCastException IllegalArgumentException Research what each exception type means and the conditions under which each occurs (i.e., is thrown). Write programs that demonstrate each type of exception being thrown (one program per exception) and provide a screen capture of the output. Name your programs as follows: NullPointerExceptionThrown, etc. Then, write a program that catches each type of thrown exception and display an error message indicating some of the details as to what that exception is. Write one program per type of exception. Name your programs as follows: NullPointerExceptionCatch, etc.Foundation in java Please provide a basic exception code. Do not use input, output. Please provide code and explain. Thank you. Write the Java code for the following: Write the InvalidGradeException class that will be used below. Write the Java program that reads an integer grade from a user and checks that it is valid (between 0 and 100). If it is invalid an InvalidGradeException will be thrown, stating what the invalid grade is. This will be caught in the main( ) method which will write a message about the invalid grade. If the grade is valid, it is written to the monitor..in java Write a program that reads integers userNum and divNum as input, and output the quotient (userNum divided by divNum). Use a try block to perform the statements. Use a catch block to catch any ArithmeticException and output an exception message with the getMessage() method. Use another catch block to catch any InputMismatchException and output an exception message with the toString() method. Note: ArithmeticException is thrown when a division by zero happens. InputMismatchException is thrown when a user enters a value of different data type than what is defined in the program. Do not include code to throw any exception in the program. Ex: If the input of the program is: 15 3 the output of the program is: 5 Ex: If the input of the program is: 10 0 the output of the program is: Arithmetic Exception: / by zero Ex: If the input of the program is: 15.5 5 the output of the program is: Input Mismatch Exception: java.util.InputMismatchException LabProgram.java…
- Calculator.java, is a simple command line calculator.Note that the program terminates if any operand is nonnumeric. Write a program with an exception handler that deals with nonnumeric operands; then write another program without using an exception handler to achieve the same objective. Your program should display a message that informs the user of the wrong operand type before exiting. (See Figure 1)In Python Please Create a custom exception class that inherits from Exception. You do not need to implement any code within this class. A pass statement is required if no code is implemented. Write a try/except statement. Raise an exception of the custom exception class you wrote. Handle the exception – i.e. Include an except suite that "catches" an exception of that type.Derive exception classes from the class you wrote in the previous exercise. Each new class should indicate a specific kind of error. For example, InvalidHourException could be used to indicate that the value entered for an hour was not an integer in the range of 1 to 12. (Also the previous answer was not preferd from the teacher cause its not simple and use def which we arent taken it)
- Java: Write a program to input 10 integers. Now check if anyone input a negative number give. If a negative number is given, then raise your own exception saying "Nope! That's a wrong input” and do nothing after that in the final block. Write try catch mechanism for catching that exception.Write a program that converts a time from 24-hour notation to 12-hour notation. To make the solution easier, a requirement is imposed on the input: It must be in xx:xx format, i.e. it must have two digits, a colon, and then another two digits. Define an exception class called TimeException. If the user enters an illegal time, like 10:65, or even gibberish, like 8&*68, your program should throw and handle a TimeException. Test your program with the file "times.txt" as input and store the result in the file "result.txt" File times.txt: 00:00 12:00 12:01 11:59 23:59 24:00 10:65 3:23 1145 8&*68 File result.txt: # 24-hour 12-hour -------------------------------------------- 1 00:00 12:00 AM 2 12:00 12:00 PM 3 12:01 12:01 PM 4 11:59 11:59 AM 5 23:59 11:59 PM 6 24:00 Time Exception 7 10:65…What is exception propagation? Give an example of a class that contains at least two methods, in which one method calls another. Ensure that the subordinate method will call a predefined Java method that can throw a checked exception. The subordinate method should not catch the exception. Explain how exception propagation will occur in your example.
