using an array write a program that will ask the user to enter a temperature for each day of the week and will find and print the average temperature, the low temperature and high temperature In Java

The approach and program to find the highest, lowest and the average temperature of a week by using arrays is given below:

Approach:

• Importing the essential package and declaring the main function within the main class.
• Creating the object of scanner class.
• Declaring and allocating the memory to the t[7] array of the double data type.
• Declaring the variables s, avg_temp of double datatype to store the sum and average of the temperatures of each day.
• Using for loop to check the condition repeatedly and storing the temperature of each day entered by the user and calculating the sum and average.
• Now, declaring the variables low_temp, high_temp to store the lowest and highest temperature stored in the array t[].
• Inside another for loop, if statements are used to store and check the highest, lowest values of the temperature and storing these values to the above variables.
• Displaying the highest, lowest and the average value of the temperatures.      

Code:

//importing the package

import java.util.*;

//declaring the main class

public class Main

{

    //declaring the main function

    public static void main(String[] args)

    {

            //creating the object of Scanner class

            Scanner input = new Scanner( System.in );

            //declaring the array

            double t [];

            //allocating memory to the array

            t = new double[7];

            //declaring the variables as per the requirement

//initializing the variables to zero      

            double s = 0;

            double avg_temp = 0;

            System.out.println("Please enter the temperature for each day: ");

        //for loop is used to check the condition repeatedely   

        for( int i = 0; i < 7; i++ )

        {

            //prompt user to take input

            System.out.print("Temperature of day " + ( i + 1 ) + ":" );

            t[i] = input.nextDouble();

            //sum of temperature

            s = s + t[i];

            //calculating the average

            avg_temp = s / t.length;

        }

            //calculating the average

            avg_temp = s / t.length;
