(JAVA)

Add an exception for divide by zero to your fraction class. Write a program to test it.

Example Output:

--------------------Configuration: --------------------

Please enter the numerator: 1

Please enter the denominator: 0

Denominator cannot be zero.

Please enter the numerator: Note, this must be handled by DenominatorIsZeroException.java.

__________________________ Write a program that reads and writes from binary or text files.

Example Output:

--------------------Configuration: --------------------

Enter the file name: kenb

Choose binary or text file(b/t): b

Choose read or write(r/w): w

Enter a line of information to write to the file: lasdklj

Would you like to enter another line? Y/N only

n

Continue? (y/n)y

Enter the file name: kenb

Choose binary or text file(b/t): b

Choose read or write(r/w): r

File contains: lasdklj

Continue? (y/n)y

Enter the file name: kent

Choose binary or text file(b/t): t

Choose read or write(r/w): w

Enter a line of information to write to the file: OOP

Would you like to enter another line? Y/N only

Y

Enter a line of information to write to the file:

Java, C++ not C. Would you like to enter another line? Y/N only n

Continue? (y/n)y

Enter the file name: kent

Choose binary or text file(b/t): t

Choose read or write(r/w):r

File contains:

OOP

Java, C++ not C.

Continue? (y/n)n

Process completed.
