Java help please!! Do NOT use break/continue in your loops.
• Do NOT use the System.exit() method to exit the program.
• Do NOT use global variables. The only global variable allowed would be the definition of
the Scanner class, or in very specific situations as strictly required by the program
requirements.
0 Write a method that returns a valid integer. The function does not have a parameter. In
our case, a valid integer is any whole number. Use the try/catch statements to handle the
error in data entry. Using a loop, make sure to ask the user for a valid integer.
1. Write a method to provide a menu of options. Make sure to call the method in step 0
(above) to get an integer for the menu choice.
2. Write a method that returns a valid decimal number. In our case a valid decimal number
is any number between 1 and 100. For example, 3.8, 90, and 2.789 are all valid input. Use
the try/catch statements to handle the error in data entry. Using a loop, make sure to ask
the user for a valid number.
3. Write a method to perform the following tasks. The method does not return a value and
does not have any parameters.
• Create an array with 10 random integers between 10 and 100, inclusive.
• Display the content of the array.
• Prompt the user to enter an index number of the array and display the
corresponding element value. If the specified index is out of bounds, handle the
exception and display the message out of bounds. HINT:
IndexOutOfBoundsException will catch such errors. For example, if the user
enters -1 or 12 for array index value, an exception must be thrown.
• Ask the user for the name of an output file. Write your own full name (do not ask
for input) as the first line of the file and write the contents of this array to this file.
4. Write a method to perform the following tasks:
• I have provided a text file named testData.txt. It contains a string of characters.
You can also test your code with the attached file of the book “pride and
prejudice” (pride_and_prejudice.txt). Write code to verify if the file exists using
try/catch block. If the file exists, calculate, and display the number of vowels (a,
e, i, o, u – case insensitive), the number of digits in the file., and the size of the
file in bytes. Hard-code the name of the file as textData.txt. If the file does not
exist, display an error message. “hard-code” simply means to assign the name of
the file as the constant “testData.txt”.
• NOTE: Simply download the file into your local folder where your source file
exists in order to use it for your testing.
5. Write a main method that tests the functionality of these methods. Make sure to display
the data to properly test your code. See the sample interaction for an example.
Sample Run/Interaction:
Enter 1 to validate an integer
Enter 2 to validate a decimal number
Enter 3 to process an array
Enter 4 to process a file
Enter 5 to exit
abc

*** Invalid entry - Try again
4.9
You entered a valid decimal number: 4.9
Enter 1 to validate an integer
Enter 2 to validate a decimal number
Enter 3 to process an array
Enter 4 to process a file
Enter 5 to exit
3
Array data:
74 17 82 25 22 72 44 41 29 33
Enter a index of the array: 12
Error, invalid index was entered.
Enter a filename to save array: 1.txt

3
Array data:
15 52 41 23 81 5 88 31 20 33
Enter a index of the array: a1
*** Invalid entry - Try again
0
The index 0 Has 15 stored.
Enter a filename to save array: 2.txt
Enter 1 to validate an integer
Enter 2 to validate a decimal number
Enter 3 to process an array
Enter 4 to process a file
Enter 5 to exit
3
Array data:
39 9 48 21 56 76 40 21 35 7
Enter a index of the array: -1
Error, invalid index was entered.
Enter a filename to save array: 3.txt
Enter 1 to validate an integer
Enter 2 to validate a decimal number
Enter 3 to process an array
Enter 4 to process a file
Enter 5 to exit
4
Number of vowels: 33
Number of Digits: 8
The file has 124 bytes
Enter 1 to validate an integer
Enter 2 to validate a decimal number
Enter 3 to process an array
Enter 4 to process a file
Enter 5 to exit
5
VERY IMPORTANT: NOTE THAT you should have 3 files named 1.txt, 2.txt, and 3.txt with data in it once
we are done running this code.
