Description: Overall, create a demo program that throws an error - MessageTooLongException - if input is more than 20 characters in length. First, create a programmer defined exception class called MessageTooLongException that extends Exception. Enter the below code into this class. Then, create a demo class which catches an error with MessageToolongException. If the user enters an acceptable number of characters (<= 20), the program should display the message, "You entered x characters, which is an acceptable length" (with the letter x replaced by the actual number of characters). Otherwise, a MessageToolongException should be thrown and caught. In either case, the program should repeatedly ask whether the user wants to enter another line or quit the program. public class MessageTooLongException extends Exception { public MessageToOLongException() { super(" ("Hessage Too Long!"); public MessageTooLongException(String message) { super (message);
Operations
In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.
Basic Operators
An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.
Division Operator
We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:
Modulus Operator
Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.
Operators
In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.
