The method should return the subscript of the element containing the value if it is found in the array. If the value is not found , the method should throw an exceptionof the Exception class with the error message “Element not found”. b) Write an exception class that can be thrown when a negative number is passed to a method.in python language , select the good example of the definition of a custom exception type? class InputErrorException: def __init__(self, value): self.value = value return value defInputErrorException:def__init__(self,value):self.value=value classInputError(Exception):def__init__(self,value):self.value=value defInputError(Exception):def__init__(self,value):self.value=valuereturnself.value
- What is exception propagation? Give an example of a class that contains at least two methods, in which one method calls another. Ensure that the subordinate method will call a predefined Java method that can throw a checked exception. The subordinate method should not catch the exception.

- 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; }Java Questions - (Has 2 Parts). Based on each code, which answer out of the choices "A, B, C, D, E" is correct. Each question has one correct answer. Thank you. Part 1 - Which pair of keywords can you use to handle an exception in Java? A. throw, catchB. try, catchC. throw, throwsD. try, finallyE. catch, finally Part 2 - Which method of the "Exception" class returns a message string? A. getError()B. getMessage()C. printMessage()D. traceMessage()E. toString()The following code is causing an exception during the runtime. class test{ public static void main(String[] args) { Object o = "Hello"; Object s = new Random(); m(o); m(s); } public static void m(Object o) { String s = (String)o; System.out.println(s.length()); }} Exception can be prevented by adding an if statement and type casting in the method m Exception can be handled by adding try-catch in the main method answers A or B both works Non of the answers
