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:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
