- Questions:1. How does exception handling work in Java?2. What are exception handling keywords in Java?3. How can you catch multiple exceptions?4. What is the difference between throw and throws keyword in Java? 5. Explain the Finally keyword in Java. PS:Please answer on your own definition and not using wikipedia.Java What is the catch phrase? What is a finally clause? How do both catch and finally work in an exception program?JAVA CODE Unchecked exceptions are exceptions that are usually the result of a mistake and we aren't expected to handle, while checked exceptions are exceptions that we reasonably expect to occur that we should handle whenever possible. Name one type of unchecked exception and one type of checked exception, and give an example of situations that might cause those exceptions to be thrown.
- In a few well-written paragraphs, discuss the use of exceptions and exception handling in programming. Your discussion should include definitions for exception, exception handler, throw signal, and catch process. Discuss why exceptions are helpful for handling runtime errors, such as division by zero.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.Hello. Please explain the ‘f()’ portion of the Java code below. If it is a function, where is it defined? What does it do in this context? Thanks, JZ // exceptions/InheritingExceptions.java // Creating your own exceptions class SimpleException extends Exception {} public class InheritingExceptions { public void f() throws SimpleException { System.out.println( "Throw SimpleException from f()"); throw new SimpleException(); } public static void main(String[] args) { InheritingExceptions sed = new InheritingExceptions(); try { sed.f(); } catch(SimpleException e) { System.out.println("Caught it!"); } } } /* Output: Throw SimpleException from f() Caught it! */
- 3. Explain the difference between a programmer-defined exception that extends the Java Exceptionclass and one that extends the Java RunTimeExceptionclass.There are three clauses in Java’s Exception Handling. What are they? What are they for? Is it possible to create your own exception? Why would you think you might need it?Answer the following questions based on your knowledge of exception handling: Why should you use exception handler in a java program? “Introducing exception handler in a program is not always good” – Explain this statement with an example. Rewrite the following inefficient java code snippet to handle the runtime exception without using the try-catch.
