Question

Please do in java as simply as possible with code available for copy and comments. Provide screenshots of code and how your incorporating the .txt file with the code.

Write a program that reads in temperatures from the text file temps.txt (file given in the assignment). Write the minimum temperature, maximum temperature and the new array (temperatures plus 10) to a new file.

The temperatures in file are:

83 87 81 88 90 92 95

Answer 1

Java code:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Arrays;
import java.util.Collections;
public class Main{

public static void main(String[] args) {
try {
FileReader read = new FileReader("File.txt");
BufferedReader bReader = new BufferedReader(read);
String numbers;
String arr[] = new String[100];
int count = 0;
while ((numbers = bReader.readLine()) != null) {
arr = numbers.split(" ");
count = arr.length;
}
int inarr[] = new int[arr.length];
for(int i=0;i<count;i++)
{
inarr[i] = Integer.parseInt(arr[i]);
  
}
int max = Arrays.stream(inarr).max().getAsInt();
int min = Arrays.stream(inarr).min().getAsInt();
read.close();

FileWriter writer = new FileWriter("File1.txt", true);
writer.write("Maximum Temparature is :"+max+"\n");
writer.write("Minimum Temparature is :"+min+"\n");
writer.write("Modified Temparatures Array:");
for(int i=0;i<count;i++)
writer.write(inarr[i]+10+" ");
writer.close();

} catch (IOException e) {
e.printStackTrace();
}
}

}

Execution screenshots:

Main.java File.txt File1.txt 6 import java.util.collections; 7. public class Main{ public static void main(String[] args) { try { FileReader read = new FileReader("File.txt"); BufferedReader bReader = new BufferedReader(read); String numbers; String arr[] = new String[100]; int count = 0; while ((numbers - bReader.readLine()) != null) { arr = numbers.split(" "); count = arr.length; int inarr[] = new int[arr.length]; for(int i=0;i<count; i++) inarr[i] = Integer.parseInt(arr[i]); int max = Arrays.stream(inarr).max().getAsInt(); int min = Arrays.stream(inarr).min().getAsInt(); read.close(); FileWriter writer = new FileWriter("File1.txt", true); writer.write("Maximum Temparature is :"+max+"\n"); writer.write("Minimum Temparature is :"+min+"\n"); writer.write("Modified Temparatures Array:"); for(int i=0;i<count;i++) writer.write(inarr[i]+10+" "); writer.close(); } catch (IOException e) { e.printStackTrace(); }
