Given the following code, the output is __. try { Integer number = new Integer("1"); System.out.println("An Integer instance."); } catch (Exception e) { System.out.println("An Exception."); }   Group of answer choices A- An Exception. B- 1 C- Error: Exception D- An Integer instance. E- None of the options

Consider the following method: public static Exception convert (Exception e) String msg - e.getMessage (): NullPointerException npe - new NullPointerException (msg); return npe; Question 4 What is the specific type of the reference value returned by this method? Select all that apply. O1llegalArgumentException Object NullPointerException Вхсеption

3-19 Please write a CHECKED EXCEPTION in Java Code per the instructions and make sure your code compiles before submitting. Thank you!

-Modify your parameter constructors to call your set methods. This will cause validation of the parameter.-Create an exception class named TractorException.-Modify your setters to throw TractorException if invalid values are passed in. You may also need to add a throws clause to your parameter constructors. This way we will not have any print methods in our Tractor object defining class-Modify your main method to try and catch exceptions. It should catch TractorExceptions and general Exceptions and display an appropriate message   import java.util.*; class TestException {     public static void main(String s[]) {            Scanner scanner = new Scanner(System.in);                boolean valid=false;                // validation loop        while (!valid) {           try {               System.out.println("Enter integer:");               int number = scanner.nextInt();  // may throw an exception               System.out.println("You entered "+ number);               valid=true;…

What outcomes are possible in the event that an exception is thrown outside of a try block?

Java question Write a Thermostat class such that a user of the Thermostat class can create an objectof Thermostat and set it to the desired temperature within a pre-specified range. If theuser tries set the temperature outside this range it should throw a TemperatureTooHighor TemperatureTooLow exception. Use inheritance to create an exception superclassTemperatureOutofRange and subclasses TemperatureTooHigh andTemperatureTooLow.Sample Tester code:Thermostat t = new Thermostat(0, 100);t. setTemp(50); // Should be OK.t.setTemp(150); // Should throw TemperatureTooHigh exception.t.setTemp(-50); // Should throw TemperatureToolLow exception.Write a Tester class to demonstrate throwing and catching of exceptions. Show that thecatch specifying the superclass catches the subclass exceptions. The order of exceptionhandlers is important. If you try to catch a superclass exception type before a subclasstype, the compiler would generate errors. Also show the re-throwing of exceptions.
