- Phase Two: Exceptions Handling Part and interface (1) Add exception handling for all classes that mentioned in phase 1 (section 1): A. Checked exceptions B. Unchecked exceptions Includes: general exceptions, invalid input, out of index for array, so on. C. Create one interface includes 2 methods that can be implement with any class.Please explain what each line of code does by providing comments. Java Intellij Project. Choose any program from this semester that accesses a file, but that does not use try-catch blocks to handle file not found exceptions. The program may be one you wrote or a sample provided by your instructor. Add a try and catch block to take the exception. You can decide what the handler does. It could simply print a message – such as on the screen in the IDE or a JOptionPane error message dialog box – or it could allow the user to enter the correct file name. Add comments to the beginning of the project code describing what you did and how it works.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();…
- What is the value of the expression max().) O None It raises a ValueError exception. O It raises an IndexError exception.What is a throw point? 2. What is an exception handler? 3. Explain the difference between a try block and a catch block. 4. What happens if an exception is thrown, but not caught? 5. Complete the following function that searches a numeric array for a specified value. The function should return the subscript of the element containing the value if it is found in the array. If the value is not found, the function should throw an exception. int searchArray(int array[], int size, int value){ int index = 0; // Used as an index to search array int subscript = -1; // To record position of search value while (index < size && subscript == -1) { if (array[index] == value) // If the value is found ___________________________________________________ ___________________________________________________ } if (subscript == -1) ___________________________________________________ return subscript; } Bonus…Define a class called GATE consisting of members Name, College, Qualification, Email, and CGPA. Define a function called read() to receive values for the above members. Create custom defined exceptions “InvalidEmailException”, “InvalidCGPA” and “NotEligibleQualification”.Raise “NotEligibleQualification” if the qualification is not any of these values: B.Tech / BE.Raise “InvalidCGPA” if the CGPA is not with in range 0 to 10.Raise “InvalidEmailException” if the email-id doesn’t contain a ‘@’ or ‘.’ symbol in the appropriate places.
- QUESTION 6 What would not cause an exception to be thrown from a cast? (Choose all that apply) A. If precision is lost due to the cast (example: double to int) B. If the object is cast to a superclass of its current type C. If the object was never instantiated as the object that it is being cast to or one of its subclasses D. If the object being cast is nullPost a total of 3 substantive responses over 2 separate days for full participation. This includes your initial post and 2 replies to classmates or your faculty member. Due Day 3 It’s important to program your code efficiently.

- Question 3 Which statement is true about exception handling? O The override specifier overrides the normal stack unwinding process. O Exception handling should be used sparingly, when other methods of error checking are available. O It moderately improves the speed performance of most programs. O Exceptions are ignored by any function labeled noexcept that throws an exception. O It is an example of RAII.MCQ 1 An exception may be handled in a variety of forms in a Java application. None of the above is NOT a possible way for a Java programme to treat an exception?a. disregard the exclusionb. Use try to capture phrases to address exceptions as they occur.c. pass the violation to another process where it can be treated; d. pass the exception to a predefined Exception class to be handlede. Both of these are acceptable methods of dealing with an anomaly.Modify the MilTime class given under Final exam module. The class should implement the following exceptions: BadHour Throw when an invalid hour (< 0 or > 2359) is passed to the class. BadSeconds Throw when an invalid number of seconds (<0 or > 59) is passed to the class. Demonstrate the class in a driver program. Demo in the main function. the file: // MillTIme.cpp//#include "stdafx.h"#include <iostream>using namespace std;class Time{protected: int hour; int min; int sec;public: Time(int h, int m, int s) { hour = h; min = m; sec = s; } int getHour() { return hour; } int getMin() { return min; } int getSec() { return sec; }}; class MilTime : public Time{private: int milHours; int milSeconds;public: MilTime(int h = 0, int s = 0) : Time(0, 0, s) { if (h < 0 || h > 2359) { cout << "Hours must be in the range 0 - 2359.\n"; milHours = h;…
