What are the boundary values for the following precondition, and which of the boundary values represent exceptions that should be thrown? @precondition ghz >= 5

Choose all of the statement(s) which are TRUE about exceptions and exception handling. Checked exceptions indicate abnormal conditions that cannot be recovered at runtime. Checked exceptions are abnormal conditions that arise in areas outside the immediate control of the program. Unchecked exceptions indicate abnormal conditions that cannot be recovered at runtime. It is desirable for unchecked exceptions to be thrown to the Java Virtual Machine so it will print a stack trace for debugging purposes. Checked exceptions are due to bugs in the code. Unchecked exceptions are abnormal conditions that arise in areas outside the immediate control of the program. O Unchecked exceptions are due to bugs in the code.

Describe the purpose and use of the "try-catch" block in exception handling.

What results are feasible if an exception is raised outside of a try block?

-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;…

Suppose a catch handler with a precise match to an exception object type is available. Under what circumstances might a different handler be executed for exception objects of that type?

First, create the custom exception class called OutOfStockException by creating a new class that extends the Exception class The class has a single constructor that takes a single argument, a string called message. The message argument is passed to the parent class (Exception) via the super keyword. Create the Store class and import the java.util.HashMap and java.util.Map classes The Store class is defined with a private Map called products, which is used to store the product names and their corresponding quantities. Create a default constructor that initializes the products map with three items: "apple", "banana", and "orange", with respective quantities of 10, 5, and 0. Define thepurchase method , which takes two arguments: a product name and a quantity to be purchased. This method throws an OutOfStockException if either the specified product is not available in the store or if the requested quantity is greater than the quantity available in stock. The method first…
