Question

Write a program that uses a two-dimensional array to store the highest and lowest temperatures for each month of the year. Prompt the user for 12 months of highest and lowest. Write two methods : one to calculate and return the average high and one to calculate and return the average low of the year. These methods MUST be your original code. Your program should output all the values in the array and then output the average high and the average low.a) Function getData: This function reads and stores data in the two-dimensional array.
b) Function averageHigh: This function calculates and returns the average high temperature for the year.
c) Function averageLow: This function calculates and returns the average low temperature for the year.
d) Function indexHighTemp: This function returns the index of the highest high temperature in the array.
e) Function indexLowTemp: This function returns the index of the lowest low temperature in the array."

Answer 1

Answer:

The Java code is given below with appropriate comments

Explanation:

import java.util.Scanner;

public class Temperature {

 

  public static void main(String[] args)

  {

      // declaring the temperatures array

      double[] maxTemp = new double[12];

      double[] lowTemp = new double[12];

      double avgHighTemp = 0;

      double avgLowTemp = 0;

     

      Scanner kb = new Scanner(System.in);

      System.out.println("Please enter the highest and lowest temperatures");

      System.out.println("of each month one by one below\n");

     

      // inputting the temperatures one by one

      for(int i = 0; i < 12; i++)

      {

          System.out.print("Please enter the highest temperature for month #" + (i+1) + ": ");

          maxTemp[i] = Integer.parseInt(kb.nextLine());

          System.out.print("Please enter the lowest temperature for month #" + (i+1) + ": ");

          lowTemp[i] = Integer.parseInt(kb.nextLine());

          System.out.println();

      }

      avgHighTemp = getAvgHighTemperature(maxTemp);

      avgLowTemp = getAvgLowTemperature(lowTemp);

      System.out.printf("Average high temperature is: %.2f\n", avgHighTemp);

      System.out.printf("Average low temperature is: %.2f\n", avgLowTemp);

     

  }

 

  // method to calculate the average high temperature

  public static double getAvgHighTemperature(double[] highTemp)

  {

      double total = 0;

      for(int i = 0; i < 12; i++)

      {

          total += highTemp[i];

      }

      return total/12;

  }

 

  // method to calculate the average low temperature

  public static double getAvgLowTemperature(double[] lowTemp)

  {

      double total = 0;

      for(int i = 0; i < 12; i++)

      {

          total += lowTemp[i];

      }

      return total/12;

  }

}
