- This programming assignment involves learning about some of the common exceptions that occur in Java programs. Consider the following exception types: NumberFormatException ArrayIndexOutOfBoundsException FileNotFoundException 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). Write 3 procedural programs and 1 Object Oriented Program. They can be very simple but make them up. You should write your code so that each exception type is forced to occur. Name your programs so that we can determine which exception you are using in the code. Example FileNotFoundException FileExists.java or something creative. 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. They can be…A custom exception type is usually defined by: inheriting from the exception class. O inheriting from the try block. a function definition within the except block. a class definition within the finally block.Write a Month class that holds information about the month. Write exception classes for the following error conditions:• A number less than 1 or greater than 12 is given for the month number.• An invalid string is given for the name of the month.Modify the Month class so that it throws the appropriate exception when either of these errors occurs. Demonstrate the classes in a program.
- Time Converter 1. Write a program that converts dates from a numerical month-day format to alphabetic month-day format. IE 1/31 or 01/31 would have an output of January 31. 1. User enters the month and day as a single string. It is then converted. (10%) 2. Create 2 exception classes (20%) 1. MonthException thrown for invalid months 2. DayException-thrown for invalid days for the given month 3. You can assume Feb is always 28 days 2. This should run in a for loop and end when a user is done entering dates (70%)Develop an exception class named InvalidMonthException that extends the Exception class. Instances of the class will be thrown based on the following conditions: The value for a month number is not between 1 and 12 The value for a month name is not January, February, March, … December Develop a class named Month. The class should define an integer field named monthNumber that holds the number of a month. For example, January would be 1, February would be 2, and so forth. In addition, provide the following methods: A no-argument constructor that sets the monthNumberto 1. An overloaded constructor that accepts the number of the month as an argument. The constructor should set the monthNumberfield to the parameter value if the parameter contains the value 1 – 12. Otherwise, throw an InvalidMonthException exception back to the caller. The exception should note that the month number was incorrect. An overloaded constructor that accepts a string containing the name of the month,…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.
- Define an exception class called CoreBreachException. The class should have a default constructor. If an exception is thrown using zero-argument constructor, getMessage should return "Cor Breach Evacuation Ship!" The class should also define a constructor having a single parameter of type String. If an exception is thrown using constructor, getMessage should return the value that was used as an argument to constructor.Java Questions - (Has 2 Parts). Based on each code, which answer out of the choices "A, B, C, D, E" is correct. Each question has one correct answer. Thank you. Part 1 - Which pair of keywords can you use to handle an exception in Java? A. throw, catchB. try, catchC. throw, throwsD. try, finallyE. catch, finally Part 2 - Which method of the "Exception" class returns a message string? A. getError()B. getMessage()C. printMessage()D. traceMessage()E. toString()In preparation for a class Fraction, create a classNullDenominatorExceptionthat must be a checked exception whoseinstances are thrown if the denominator of an object of class Fraction is 0.
- it is a java question Write a custom exception class named StringTooLongException containing a no argument constructor and a one argument constructor.Define an exception class called CoreBreachException. The class should have a default constructor. If an exception is thrown using this zero- argument constructor, getMessage should return "Core Breach! Evacuate Ship!" The class should also define a constructor having a single parameter of type String. If an exception is thrown using this constructor, getMessage should return the value that was used as an argument to the constructor.Using Java Define a Rubric class that extends the GradedActivity class shown below. The Rubric class should determine the grade a student receives for a chapter lab. Using the following points: Algorithm: 20 points Variables: 5 points Formulas: 5 points Test Data: 15 points UML: 20 points Code: 35 points Create exception classes for 2 error conditions. You determine which errors for the exceptions. Demonstrate the class in a simple program. GradedActivity public class GradedActivity { private double score; // holds the score public void setScore (double s) { score=s; } //end method for setting the score public double getScore() { return score; }// end method to return the score public char getGrade() { // return a letter grade determined by the scores listed below char letterGrade; if (score >= 90) letterGrade = 'A'; else if (score >=80) letterGrade = 'B'; else if (score >=70)…
