Question

I need to write a program in java using two array lists. I need to program to prompt the user to enter a day of the week and return an output of a predetermined temperature for the day they selected. I also need the program the output the average of daily temperatures across the week if the user inputs "week".

So basically if i set the temperatures to something arbitrary i.e.:

Monday = 50

Tuesday = 55

Wednesday = 52

Thursday = 50

Friday = 52

Saturday = 55

Sunday = 57

And the user enters "Monday" i need the output to display something like "The temperature for Monday will be: 50 degrees"

Answer 1

import java.util.Scanner;

public class MonthTemparature {
  public static void main(String args[]){
    int arr[] = {50,55,52,50,52,55,57};
    double average = 0;
    for(int i = 0;i<arr.length;i++){
      average += arr[i];
    }
    average /= arr.length;

    Scanner scanner = new Scanner(System.in);
    System.out.println("Enter day:");
    String s = scanner.nextLine();
    if(s.equalsIgnoreCase("monday")){
      System.out.println("The temperature for "+s+" will be: "+arr[0]+" degrees");
    }
    else if(s.equalsIgnoreCase("tuesday ")){
      System.out.println("The temperature for "+s+" will be: "+arr[1]+" degrees");
    }
    else if(s.equalsIgnoreCase("wednesday ")){
      System.out.println("The temperature for "+s+" will be: "+arr[2]+" degrees");
    }
    else if(s.equalsIgnoreCase("thursday ")){
      System.out.println("The temperature for "+s+" will be: "+arr[3]+" degrees");
    }
    else if(s.equalsIgnoreCase("friday ")){
      System.out.println("The temperature for "+s+" will be: "+arr[4]+" degrees");
    }
    else if(s.equalsIgnoreCase("saturday ")){
      System.out.println("The temperature for "+s+" will be: "+arr[5]+" degrees");
    }
    else if(s.equalsIgnoreCase("sunday ")){
      System.out.println("The temperature for "+s+" will be: "+arr[6]+" degrees");
    }
    else if(s.equalsIgnoreCase("week ")){
      System.out.println("The temperature for "+s+" will be: "+average+" degrees");
    }
  }
}
