Exercise 1: Exception Basics Exceptions are used in Java to handle exceptional events (i.e. errors) that interrupt program execution. When an error occurs, an exception is thrown. Examples of errors that throw exceptions are reading input from the user that does not match the expected format. opening a file that does not exist or failure when writing to a file, integer division by zero or using invalid array indices. Exception handling involves specifying try-catch-finally blocks where the try block contains code that could cause an error, catch block contains code to deal with a specific class of exceptions, and finally block contains code that is executed whether or not an exception was thrown. Create the class Exception Basics and enter the source code that appears below. public class Exception Basics { static boolean CAUSE_EXCEPTION=true; public static void main(String args[]) { try { System.out.println("Try Block executed: "); if (CAUSE_EXCEPTION) throw new Exception("This is an exception"); System.out.println("End of the try block!"); } catch (Exception e) { System.err.println("Catch Block executed on :"+e); } finally { } System.out.println("Finally Block is executed"); } Run the code, setting CAUSE EXCEPTION=true, noting the console output, and Run the code, setting CAUSE EXCEPTION=false noting the console output.
