2. Use inheritance to create a hierarchy of Exception classes -- EndOfSentenceException, PunctuationException, and CommaExceptio

n. EndOfSentenceException is the parent class to PunctuationException, which is the parent class to CommaException. Test your classes in a Driver class with a main method that asks the user to input a sentence. If the sentence ends in anything except a period (.), exclamation point (!), or question mark (?), the program should throw a PunctuationException. If the sentence specifically ends in a comma, the program should throw a CommaException. Use a catch block to catch all EndOfSentenceExceptions, causing the program to print a message and terminate. If a general PunctuationException is caught, the program should print "The sentence does not end correctly." If a CommaException is caught, the program should print "You can't end a sentence in a comma." If there are no exceptions, the program should print "The sentence ends correctly." and terminate.

Answer:

See explaination

Explanation:

EndOfSentenceException.java

//Create a class EndOfSentenceException that

//extends the Exception class.

class EndOfSentenceException extends Exception

{

//Construtor.

EndOfSentenceException(String str)

{

System.out.println(str);

}

}

CommaException.java

//Create a class CommaException that extends the class

//EndOfSentenceException.

class CommaException extends EndOfSentenceException

{

//Define the constructor of CommaException.

public CommaException(String str)

{

super(str);

}

}

PunctuationException.java

//Create a class PunctuationException that extends the class

//EndOfSentenceException.

class PunctuationException extends EndOfSentenceException

{

//Constructor.

public PunctuationException(String str)

{

super(str);

}

}

Driver.java

//Include the header file.

import java.util.Scanner;

//Define the class Driver to check the sentence.

public class Driver {

//Define the function to check the sentence exceptions.

public String checkSentence(String str)

throws EndOfSentenceException

{

//Check the sentence ends with full stop,

//exclamation mark

//and question mark.

if(!(str.endsWith(".")) && !(str.endsWith("!"))

&& !(str.endsWith("?")))

{

//Check the sentence is ending with comma.

if(str.endsWith(","))

{

//Throw the CommaException.

throw new CommaException("You can't "

+ "end a sentence in a comma.");

}

//Otherwise.

else

{

//Throw PunctuationException.

throw new PunctuationException("The sentence "

+ "does not end correctly.");

}

}

//If the above conditions fails then

//return this message to the main function.

return "The sentence ends correctly.";

}

//Define the main function.

public static void main(String[] args)

{

//Create an object of Scanner

Scanner object = new Scanner(System.in);

//Prompt the user to enter the sentence.

System.out.println("Enter the sentence:");

String sentence=object.nextLine();

//Begin the try block.

try {

//Call the Driver's check function.

System.out.println(new

Driver().checkSentence(sentence));

}

//The catch block to catch the exception.

catch (EndOfSentenceException e)

{}

}

}

Please write a complete program to calculate monthly payment given
jasenka [17]

Explanation:

Code with comments:

#include <stdio.h>

#include <math.h>  

/* math library is required to use pow() function

First we need to create a function to calculate the Monthly Payment

It would take three inputs Rate, Years, and Principle amount

Then we converted the Rate and Months according to problem statement

pow() function is used to find (1+R)^M

Then finaly this function returns the value of Monthly Payment  */

float MonthlyPay(float R, int M, int P)

{

    R=R/1200;

    M=M*12;

   float po=pow((1+R),M);

   float PayM=(R+(R/(po-1)))*P;

    return PayM;

}

/*  In the main() function we get 3 inputs from the user Years, Rate and Principle amount

then we call the MonthlyPay function and pass it 3 inputs that we got from the user

then we calculated the total Payment by multiplying the Monthly Pay and total number of months

then we calculated the interest Amount by subtracting the Principle Amount from total Pay

Testing is performed and output result is given at the end and also attached in the image   */

int main(void)

{

    float Rate;

    int Year, Amount;

    printf("Enter Years: ");

    scanf("%d",&Year);

    printf("Enter Rate: ");

    scanf("%f",&Rate);

    printf("Enter Principle Amount: ");

    scanf("%d",&Amount);

   

    float Pay = MonthlyPay(Rate, Year, Amount);

    printf ("Monthly Payment is: %f \n", Pay);

    float totalPay=Pay*Year*12;

    printf ("Total Payment is: %f \n", totalPay);

    float interest=totalPay-Amount;

    printf ("Interest Expense is: %f \n", interest);

    return 0;

}

Output:

Enter Years: 5

Enter Rate: 7

Enter Principle Amount: 12200

Monthly Payment is: 241.572767

Total Payment is: 14494.367188

Interest Expense is: 2294.367188
