Why should we we generally use Exceptions rather than error codes? A. Error codes ensure the program crashes, while Exceptions give the user a chance to fix the exception B. Trick question: we should generally use error codes, not Exceptions. C. Error codes can be easily mistaken for legitimate output, whereas Exceptions cannot be D. Exceptions are easier to write than returning error codes

Defined Exception Handling Exception Handling is used to overcome exceptions that take place during programs’ execution in a systematic manner. For instance, dividing a number by ‘0’ is a mathematical error (not defined). As you learned in class, you can use exception handling to overcome such operations. If you write a code without using exception handling, then the output of division by zero will be shown as infinity which cannot be further processed. Consider the following code: float Division(float num, float den) {return (num / den);} int main() { float numerator = 12.5; float denominator = 0; float result; result = Division(numerator, denominator); cout << "The quotient of 12.5/0 is " << result << endl; }

What is the benefit of defining a custom exception class to be derived from the exception class?
JAVA EXCEPTION HANDLING Complete the java code below according to the instructions given. Also use the test example below: Define the exceptions that are necessary to catch the possible errors that can occur in the class Matrix • ExceptionWrongMatrixValues that is thrown in the method read() if the data on the String does not correspond to numeric values, or if the data are not consistent with the form of a matrix (e.g., the rows have different length); • ExceptionWrongMatrixDimension that is thrown in the method read() if the data on the String do not correspond to the dimension of the matrix. The numbers are separated by space. A dot in a string means the next string of text is for the next row. For example: Test Result String input="1 2 3 . 1 e 3 ."; Matrix m = new Matrix(); m.read(input); ExceptionWrongMatrixValues String input="1 2 3 . 1 2 3 4 5 ."; Matrix m = new Matrix(); m.read(input); ExceptionWrongMatrixValues String input="12312345"; Matrix m = new Matrix();…
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)
An exception is a problem that arises during the execution of a program. When an exception occurs, the program terminates abnormally. We create exception handlers to exit gracefully. Why should we program for exceptions? Using code snippets, provide an example situation where programming for exceptions gives value to the end user.

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.
What are the benefits of using the exception handling method?
Part 1 Describe how catching exceptions can help with file errors. Write a Python example that implements exception handling for any one of the file errors. Your code should use, try: except: blocks. Clearly mention the exception name in except block that you would handle. Include the code and output in your post along with necessary explanation. Part 2 Describe how you might deal with a file error if you were writing a large production program. These descriptions should be general ideas in English, not actual Python code. The code and its output must be explained technically whenever asked. The explanation can be provided before or after the code, or in the form of code comments within the code. For any descriptive type question, Your answer must be at least 150 words. Remember to post your initial response as early as possible, preferably by Sunday evening, to allow time for you and your classmates to have a discussion.

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.
