- 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. Explain how exception propagation will occur in your example.Please solve this question, JAVA language for a programming fundamentals course. This is the question in text: Write java code to implement exception handling on your own example. Use the keywords throw new, throws, try, catch, and finally in the same program. Use a static method to implement the keyword throws.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 // for input from keyboard public class MyExceptionApp { public static void main( ) throws MyDivByZeroException { Scanner kb = System.out.println("Enter two numbers for division : "); double n1 = kb.nextDouble(); double n2 = kb.nextDouble(); try{ if( n2 == 0 ) throw else System.out.println("Answer = " + n1/n2); } catch ( e){ System.out.println("Exception caught : " + e); }…

- JAVA Given a main program that searches for the ID or the name of a student from a text file, complete the findID() and the findName() methods that return the corresponding information of a student. Then, insert a try/catch statement in main() to catch any exceptions thrown by findID() or findName(), and output the exception message. Each line in the text file contains the name and the ID of a student, separated by a space. Method findID() takes two parameters, a student's name and a Scanner object containing the text file's contents. Method findID() returns the ID associated with the student's name if the name is in the file, otherwise the method throws an Exception object with the message "Student ID not found for studentName", where studentName is the name of the student. Method findName() takes two parameters, a student's ID and a Scanner object containing the text file's contents. Method findName() returns the name associated with the student's ID if the ID is in the file,…PLZ help with the following IN JAVA If a method throws an exception, and the exception is not caught inside the method, then the method invocation: terminates transfers control to the catch block transfers control to the exception handler none of the abovevoid foo () { try { throw new Exception1 (); print (" A "); throw new Exception2 (); print (" B "); } catch ( Exception1 e1 ) { print " handler1 "; } print (" C "); throw new Exception2 (); } void main () { try { try { foo (); print (" D "); } catch ( Exception1 e1 ) { print " handler2 "; } print (" E "); } catch ( Exception2 e2 ) { print " handler3 "; } } Write down the output of the program and justify why it is the output. Instead of the “replacement” semantics of exception handling used in modern languages, a very early design of exception handling introduced in the PL/I language uses a “binding” semantics. In particular, the design dynamically tracks a sequence of “catch” blocks that are currently active; a catch block is active whenever the corresponding try block is active. What will be the output of the following program if the language uses the “binding” semantics? Give the reasoning for your answer.
