Answer:

Jacob Gardner - Lucas Robinson - Caden Boothe - Michael Armstrong

Explanation:

According to clue 4, Lucas's house is not the first, and he has a house on his right, so it can only be house 2 or house 3. Therefore, Caden's house (which is on the right right of Lucas's), it can only be house 3 or house 4.

In turn, track 1 says that Michael's house is not next to Lucas's, so it can be 1 (if Lucas's house is 3) or 4 (if Lucas's house is in 2).

Track 2 says that there is a house before Michael's, which eliminates the possibility that Michael's house is number 1 (there would be no previous house). Thus, in addition, Lucas's house turns out to be 2 (Michael's house is not next door) and Caden's is 3, while Jacon's is house 1.

Jacob - Lucas - Caden - Michael

In turn, regarding surnames, clue 2 says that Robinson's house is after Gardner's and before Michael's. Thus, Robinson can be the last name of Jacob or Lucas, and Gardner that of Lucas or Caden. Now, since Boothe's house is just before Armstrong's, the order would be as follows:

Jacob Gardner - Lucas Robinson - Caden Boothe - Michael Armstrong

What is the energy conversion of solar water heaters?
Gelneren [198K]
A liquid-to-liquid heat exchanger uses a heat-transfer fluid that circulates through the solar collector, absorbs heat, and then flows through a heat exchanger to transfer its heat to water in a storage tank. Heat-transfer fluids, such as antifreeze, protect the solar collector from freezing in cold weather.

import java.io.IOException;

import java.util.Scanner;

import java.util.StringTokenizer;

public class SecretMessage {

public static void main(String[] args)throws IOException

{

File file = new File("secret.txt");

StringBuilder stringBuilder = new StringBuilder();

String str; char ch; int numberOfTokens = 1; // Changed the count to 1 as we already consider first workd as 1

if(file.exists())

{

Scanner inFile = new Scanner(file);

StringTokenizer line = new StringTokenizer(inFile.nextLine()); // Since the secret.txt file has only one line we dont need to loop through the file

ch = line.nextToken().toUpperCase().charAt(0); // Storing the first character of first word to string builder as mentioned in problem

stringBuilder = stringBuilder.append(ch);

while(line.hasMoreTokens()) { // Looping through each token of line read using Scanner.

str= line.nextToken();

numberOfTokens += 1; // Incrementing the numberOfTokens by one.

if(numberOfTokens == 5) { // Checking if it is the fifth word

ch = str.toUpperCase().charAt(0);

stringBuilder = stringBuilder.append(ch);

numberOfTokens =0;
