- 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();…Write code for DivideByZero exception along with sample program using it. Topic: Exception HandlingHow does method overriding interact with exception handling? Explain how overridden methods can throw exceptions.
- 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.mplement the loan calculator discussed in class. The application should be able to handle Exceptions and be very similar to the image below.What is the benefit of defining a custom exception class to be derived from the exception class?
- How would you solve question 11 while also throwing exceptions if n is less than zero?2. An exception will generate a "call stack trace" that lists a. the active methods in the order in which they were invoked b. the active methods of the opposite order in which they were invoked c. the values of all instance data of the object where the exception was raised d. the values of all instance data of the object where the exception was raised as well as the local variables and parameters of the meth e. the name of the exception thrown3. Write the difference between throw and throws keywords used for exception handling. 4. What is exception propagation? How to handle exception in child class.
- 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)…What are the benefits of using the approach for managing exceptions, and why should one do so?Explain exception test
