Question
Chapter 9, Problem 16PC
Program Plan Intro
Morse Code Converter
Program Plan:
The detail of “MorseCodeConverter” class is shown below:
- In the “main()” method,
- Declare the variable.
- Create an object for Scanner class.
- Read the string input from the user.
- Create an object for Morse object to invoke parameterized constructor.
- Call the getMorseCode() method to display the Morse code.
The detail of “Morse” class is shown below:
- Declare the required variables.
- In the “Morse()” parameterized constructor,
- Declare and initialize the required variables.
- The while loop executes until the “index” is less than length of input. If yes,
- Get the morse code for character and then append it into “mcode” with newline.
- Increment “index” by “1”.
- In the “toMorse()” method,
- Declare the variable.
- The while loop executes until the find character in array. If yes, increment “index” by “1”.
- Check whether “index” is greater than or equal to “NUM_CHARS”. If yes, set the value as character was not found.
- Otherwise, get the morse code.
- Return the morse value.
- In the “getOriginal()” method,
- Return the original string.
- In the “getOriginal()” method,
- Return the converted morsecode character.

InitialsWrite a python program that gets a string containing a person’s first, middle, and last names, anddisplays their first, middle, and last initials. For example, if the user enters John William Smith,the program should display J. W. S.
Lab Activity for the students:
Exercise 5: Write a program that asks the user to input a letter. The program finds and prints if the letter is
uppercase or lowercase. Then, the program asks the user to input a string and get a three-character substring
from the beginning of the string. (1 Mark )
Example : If the inputs are 'y' and "Community". Then, the program will print:
y is lowercase
The substring is: Com
