Answer 1

Complete Question

Write an expression to detect that the first character of userInput matches firstletter

import java.util.Scanner;

public class CharMatching

{

public static void main (String [] args)

{

Scanner scnr = new Scanner (System.in);

string userInput;

char firstLetter;

userInput = scnr.nextLine();

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

if ( = firstLetter ) {// Your solution goes here

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

else { System.out.println("No match: " + firstLetter); }

return;

}

}

Answer:

Replace if( = firstLetter) with the following

if(userInput.CharAt(0) == firstLetter)

What the above code segment does is that it extracts the first character of userInput and compare it with the content of firstLetter

The full program becomes

import java.util.Scanner;

public class CharMatching

{

public static void main (String [] args)

{

Scanner scnr = new Scanner (System.in);

string userInput;

char firstLetter;

userInput = scnr.nextLine();

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

if(userInput.CharAt(0) == firstLetter){

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

else { System.out.println("No match: " + firstLetter); }

return;

}

}
