Question
Chapter 30, Problem 30.17PE
Program Plan Intro
Count consonants and vowels
Program Plan:
- Import the necessary packages into program.
- Define the class named “Exercise30_17”.
- Define the main method.
- Using “if…else” condition, check the first argument. If the file name is incorrect then print appropriate error message.
- Exit the system.
- Assign the first argument value into variable “name_file”.
- Assign the vowel set into variable using “HashSet<>” class.
- Find the number of vowels and consonants using “Stream” class.
- Define the method “toCharacterArray()” which takes array list as parameter.
- Declare the character variable “ans” in type of character.
- Using “for” loop, assign all list values into “ans[]”.
- Return the value of “ans”.
- Define the main method.

As with most problems with number representations, errors can be intermittent. Sometimes the code will work as expected, and other times it will behave in a manner that seems to be totally arbitrary. Consider the following code fragment that makes use of the fact that shifting a value left by one place multiplies the number by 2. By passing in the number to be multiplied and the power of 2 to multiply it by (for example 4 = 22) the correct answer should be passed back from the function after the results are printed for the user to examine. signed int mult_2_to_n (signed int num, int n) { signed int result; result = num << n; printf("%d multiplied by 2^%d %d\n", num, n, result); return result; } Using a signed number as the manipulated integer may cause an error in some cases.

- Modified Programming ). (Count vowels and consonants, file input, nested-loops, switch statement) Assume that letters A, E, I, O and U are the vowels. Write a program that reads strings from a text file, one line at a time, using a while-loop. You do the following operations within each loop: • Read one line from the input file and store it in a string; Count the number of vowels and consonants (using either while-loop or for-loop) in the file string. The while-loop will terminate when the end-of-file is reached. After the loop is finished, the program displays the total number of vowels and consonants in the text file.
