Java Write An Expression To Detect That The First Character Of Userinput Matches Firstletter.

The given source code is an illustration of characters and strings in Java program.

To complete the code segment, the comment /* Your solution goes here */ in the program, should be replaced with any of the following expressions:

Character.toUpperCase(firstLetter)==Character.toUpperCase(userInput.charAt(0))
Character.toLowerCase(firstLetter)==Character.toLowerCase(userInput.charAt(0))

Using the first instruction above

Variable firstLetter will first be converted to upper case
The first character of userInput will then be extracted using charAt(0)
The first character is then converted to upper case
Lastly, both characters are compared

So, the complete code (where comments are used to explain each line) is as follows:

//This imports the Scanner library

import java.util.Scanner;

//This defines the program class

public class Main {

//This defines the program method

public static void main (String [] args) {

//This creates a Scanner object

Scanner scnr = new Scanner(System.in);

//This declares variables userInput and firstLetter

String userInput; char firstLetter;

//This gets input for userInput

userInput = scnr.nextLine();

//This gets input for firstLetter

firstLetter = scnr.nextLine().charAt(0);

//This checks if the first letter of userInput matches with variable firstLetter

if (Character.toUpperCase(firstLetter)==Character.toUpperCase(userInput.charAt(0))){

//If yes, found match is printed

System.out.println( “Found match: “+firstLetter); }

else{

//If otherwise, no match is printed

System.out.println(“No match: “+ firstLetter);

}

}

}//Program ends here.

C++ Write An Expression To Detect That The First Character Of Userinput Matches Firstletter.

if (/* Your solution goes here */) {
cout << “Found match: ” << firstLetter << endl;
}
else {
cout << “No match: ” << firstLetter << endl;
}

return 0;
}
