- PLZ help with the following: True/False In java it is possible to throw an exception, catch it, then re-throw that same exception if it is desired GUIs are windowing interfaces that handle user input and output. An interface can contain defined constants as well as method headings or instead of method headings. When a recursive call is encountered, computation is temporarily suspended; all of the information needed to continue the computation is saved and the recursive call is evaluated. Can you have a static method in a nonstatic inner class?True or False: IOException serves as a superclass for exceptions that are related to programming errors, such as an out-of-bounds array subscript.a) Write a method in java that searches a numeric array for a specified value. The method should return the subscript of the element containing the value if it is found in the array. If the value is not found , the method should throw an exceptionof the Exception class with the error message “Element not found”. b) Write an exception class that can be thrown when a negative number is passed to a method.
- Challenge 1: Division.java You have to implement a Division class that divides two numbers given by the user. The program should handle exceptions that could be thrown during operation: If the second number is 0 If any of the numbers is not a valid number, such as a letter.Rules: Corner cases. Throw the specified exception for the following corner cases: Throw an IllegalArgumentException if the client calls either addFirst() or addLast() with a null argument. Throw a java.util.NoSuchElementException if the client calls either removeFirst() or removeLast when the deque is empty. Throw a java.util.NoSuchElementException if the client calls the next() method in the iterator when there are no more items to return. Unit testing. Your main() method must call directly every public constructor and method to help verify that they work as prescribed (e.g., by printing results to standard output). Performance requirements. Your implementation must achieve the following worst-case performance requirements: A deque containing n items must use at most 48n + 192 bytes of memory, not including the memory for the items themselves. Each deque operation (including construction) must take constant time. Each iterator operation (including construction) must take…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.
- Modify the attached code: Create a new class called CalculatorWithMod. This class should be a sub class of the base class Calculator. This class should also have an additional method for calculating the modulo. The modulo method should only be seen at the sub class, and not the base class! Include exception handling for instances when dividing by 0 or calculating the modulo with 0. You would need to use throw, try, and catch. The modulo (or "modulus" or "mod") is the remainder after dividing one number by another.Example: 20 mod 3 equals 2Because 20/3 = 6 with a remainder of 2 Refer also to the attached sample outputs:Create a flowchart and modify the code. INSTRUCTION: Create a new class called CalculatorWithMod. This class should be a sub class of the base class Calculator. This class should also have an additional method for calculating the modulo. The modulo method should only be seen at the sub class, and not the base class! Include exception handling for instances when dividing by 0 or calculating the modulo with 0. You would need to use throw, try, and catch. The modulo (or "modulus" or "mod") is the remainder after dividing one number by another.Example: 20 mod 3 equals 2Because 20/3 = 6 with a remainder of 2 CODE TO COPY: #include <iostream> using namespace std; class Calculator{public:Calculator(){printf("Welcome to my Calculator\n"); } int addition(int a, int b);int subtraction(int a, int b);int multiplication(int a, int b);float division(int a, int b);}; int Calculator::addition(int a, int b){return (a+b);} int Calculator::subtraction(int a, int b){return (a-b);} int…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,…
- Java Problem:Create a Class named Bishop. Make sure the class cannot be inherited. If there have already been 5 objects initiated for this class, trying to initiate the 6th object, the constructor will throw a user-defined exception BishopCreationLimitExceeded. This class has an instance method named printObjectNumber which will print the object creation sequence number for the object for which you are calling the method as follows: This Bishop Object number is 3. Here, 3 is the object creation sequence number that is the third call to new Bishop() in your code that initiated the object. The BishopCreationLimitExceeded class sets the exception message (using super call in the constructor) as follows: The maximum number of bishop objects can be 5. You can define instance variables in the Bishop class if you need them.Java question Write a Thermostat class such that a user of the Thermostat class can create an objectof Thermostat and set it to the desired temperature within a pre-specified range. If theuser tries set the temperature outside this range it should throw a TemperatureTooHighor TemperatureTooLow exception. Use inheritance to create an exception superclassTemperatureOutofRange and subclasses TemperatureTooHigh andTemperatureTooLow.Sample Tester code:Thermostat t = new Thermostat(0, 100);t. setTemp(50); // Should be OK.t.setTemp(150); // Should throw TemperatureTooHigh exception.t.setTemp(-50); // Should throw TemperatureToolLow exception.Write a Tester class to demonstrate throwing and catching of exceptions. Show that thecatch specifying the superclass catches the subclass exceptions. The order of exceptionhandlers is important. If you try to catch a superclass exception type before a subclasstype, the compiler would generate errors. Also show the re-throwing of exceptions.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.
