Question
Chapter 9.3, Problem 26STQ
Program Plan Intro
Exception:
- It is nothing but an undesirable or unexpected event that occurs at run time which interrupts the normal flow of the
program ’s commands. - Exception handling is a
mechanism that handle runtime errors like “ClassNotFoundException”, “SQLException”, and so on. - An advantage of exception handling is to maintain a flow of the program.
- An exception can be handled using “try” and “catch” block.
Types of exceptions:
There are two types of exceptions. They are:
- Checked Exception:
- A class that inherits a “Throwable” class except “RunTimeException” and “Error” are called as checked exceptions.
- Example: “IOException”
- Unchecked Exception:
- A class that inherits a “RunTimeException” class is called as unchecked exceptions.
- Example: “ArrayIndexOutOfBoundException”
“throws” clause:
- This clause is used to declare the exception. This provides information to the programmer that the program might produce an exception so it is better to give the exception handling code which maintains the normal flow of the program.
- It is usually given in the method header.
Syntax:
Method_Name throws ExceptionName
{
//statements
}

Write a class TimeOfDay that uses the exception classes defined in the previous exercise. Give it a method setTimeTo(timeString) that changes the time if timeString corresponds to a valid time of day. If not, it should throw an exception of the appropriate type. [Java]
Java Foundations :
Please provide code and explain. Thank you.
Write the code segments in main( ) and in methodA( ) for the following scenario:
main( ) passes methodA an int variable called a.
methodA generates an exception, but does not deal with it, if a is not between 1 and 100.
5. Write a JAVA program to define a static method checkPT() to receive 3 positive integer
parameters and checks whether they form Pythagorean triplet. If yes, display appropriate
message, otherwise, throw custom exception called InvalidPythagoreanTripletException.
The checkPT() method does not handle the exception thrown.
Write main method in the same class to read 3 integers and make call to checkPT()
method infinitely. The
InvalidPythagoreanTripletException exception object. Use throw, throws, try and catch
keywords appropriately in the program. Also illustrate re-throwing an exception in the
main method handles the exception by displaying the
program.

- Define a public static method called squareArea that takes one double argument called length,which is the side length of a square. This method will return the area of the square (side * side), which is a double. Do not define a class. You may only use techniques and data structures that have already been covered in this class. Do not include any exception handling. For example, squareArea(5.0) should return 25.0.arrow_forwardplease solve this important, thanks.arrow_forwardhttps://youtu.be/4hAoK54Pfdc Here is a video regarding the kit component.arrow_forward

NegativeNumberException as a derived class of Standard Library class logic_error, that is used to detect if the user entered a negative number as a grade. 3. InvalidGradeException as a derived class of Standard Library class logic_error, that is used to detect if a user entered an invalid input (grade greater than total grade).
