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;

}

}

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;

}

}

Explanation:

x+2 because it just doubles hon so the pattern can actually tell you the expression.

so for example,

if x=2 then 2+2 is 4

if x=4 then 4+4 is 8

and so on and so forth.

i really hope that this makes sense and you out in a way hon: )
