Question

Please help my finish problem 1. Please edit my coding (shown below) about the highestTemps and lowestTemps.

Problem 1 Write a program called Temperatures that will read in a user specified number of temperatures into a double array. Then print the highest, lowest and average temperature. Write five separate methods in addition to the main method- one each for readTemps, highestTemp, lowestTemp, averageTemp and printTemps. The printTemps method should be a void method (it returns nothing) and should accept a doublel 1 as input. The readTemps method should create and return a doublel 1 and does not take any arguments. The other three should accept a doublel ] as input and return a double value. Make sure you test your program using temperatures bpth above and below zero. Temperatures that you output should be formatted to display 2 places past the decimal point. Sample run: Enter the number of temperatures: 7 Please enter 7 temperatures... Enter temperature #1 of 7: 77 Enter temperature #2 of 7: 65 Enter temperature #3 of 7: 69 Enter temperature #4 of 7: 82 Enter temperature #5 of 7: 70 Enter temperature #6 of 7: 57 Enter temperature #7 of 7: 76 The average temperature is 70.86 The highest temperature is 82.00 The lowest temperature is 57.00 The above statistics are based on the following temperatures: Temperature #1: 77.00 Temperature #2: 65.00 Temperature #3: 69.00 Temperature #4 : 82.00 Temperature #5: 70.00 Temperature #6: 57.00 Temperature 17: 76.00

import java.util.Scanner;

public class Temperatures{

public static void main(String[] args) {

double[] Temperature = readTemps();

System.out.printf("\nThe average is %.2f%n", averageTemps(Temperature));

highestTemps(Temperature);

lowestTemps(Temperature);

System.out.println("\nThe above statistics are based on the following temperatures: ");

printTemps(Temperature);

}

private static double[] readTemps(){

Scanner keyboard = new Scanner(System.in);

System.out.printf("Enter the number of temperatures: ");

int numTemps = keyboard.nextInt();

double[] Temps = new double[numTemps];

System.out.println("Please enter "+Temps.length+" Temperatures: ");

for(int i=0; i<Temps.length; i++){

System.out.print("Enter grade #"+(i+1)+" of "+Temps.length+": ");

Temps[i] = keyboard.nextDouble();

}

return Temps;

}

double sum = 0.0;
