Conditionals and Loops
Transcribed Image Text:Conditionals and Loops
2. Design and implement an application that reads a string from the user, then determines and displays how many (of each) of the five vowels
(a, e, i, o, and u) appear in the entire string. Have a separate counter for each vowel. Also count and print the number of non-vowel
characters. The app should handle both lowercase and uppercase vowels. The logic must include a switch-case structure to determine
which counter to increment.
Hint: Use the charAt method of the String class to examine each character of the input.
Testing: Build a test plan separately so you can predict and show that your program is working correctly. You need to determine a selection
of inputs, such as something with no vowels, only a single letter "a," and so on. A key requirement is to prove that each counter is
functioning independently of the others.
