Write a JAVA PROGRAM to create a user defined exception class. In this, a constructor of InvalidGradeException accepts a string as an argument. This string is passed to constructor of parent class Exception using the super () method. Also the constructor of Exception class can be called without using a parameter and calling super () method is not mandatory. WRITE JAVA PROGRAM only, and give screenshot of sample run

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.
Using JAVA (Constructor Failure) Write a program that shows a constructor passing information about constructor failure to an exception handler. Define class SomeClass, which throws an Exception in the constructor. Your program should try to create an object of type SomeClass and catch the exception that’s thrown from the constructor.
Java Define the class InvalidSideException, which inherits from the Exception class. Also define a Square class, which has one method variable -- an int describing the side length. The constructor of the Square class should take one argument, an int meant to initialize the side length; however, if the argument is not greater than 0, the constructor should throw an InvalidSideError. The Square class should also have a method getArea(), which returns the area of the square.Create a Driver class with a main method to test your classes. Your program should prompt the user to enter a value for the side length, and then create a Square object with that side length. If the side length is valid, the program should print the area of the square. Otherwise, it should catch the InvalidExceptionError, print "Side length must be greater than 0.", and terminate the program. Standard output: Enter·side·length·of·square:16↵ 256↵

Complete the following Java program by typing in the missing statements in the space provided. This program inputs a value/s from user, and displays the result of some operation. If the operation generated an exception / error, it is handled by the user defined exception class. The main method in the application class is declared to throw a user-defined exception which will take care of the exception. import Il for input from keyboard public class MyExceptionApp { public static void main( ) throws MyNegNoException { Scanner kb = System.out.printin("Enter a number for squar-root : "); double n = kb.nextDouble(); try{ if( n< 0) throw else System.out.printin("Squar-root ="+ Math.sqrt(n) ); } catch ( e){ System.out.printin("Exception caught:" + e); } System.out.printlin("Program terminated normally . "); } } Il definition of MyNegNoException class class MyNegNoException| { // default constructor is required { Il a constructor with String argument is also required System.out.printin(msg);
Java Foundations : Please provide code and explain. Thank you. Write the code segments in main( ) and in methodA( ) for the following scenario: main( ) passes methodA an int variable called a. methodA generates an exception, but does not deal with it, if a is not between 1 and 100.
Use inheritance in JAVA to create an exception superclass(called ExceptionA) and exception subclasses ExceptionB and ExceptionC, where ExceptionB inherits from ExceptionA and ExceptionC inherits from ExceptionB. Write a program to demonstrate that the catch block for type ExceptionA catches exceptions of types ExceptionB and ExceptionC.
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)
Using JAVA (Catching Exceptions with Superclasses) Use inheritance to create an exception superclass (called ExceptionA) and exception subclasses ExceptionB and ExceptionC, where ExceptionB inherits from ExceptionA and ExceptionC inherits from ExceptionB. Write a program to demonstratethat the catch block for type ExceptionA catches exceptions of types ExceptionB and ExceptionC.
