Using Dr Java
Objective:
Write a program that takes in temperatures for 10 days and stores it in an array. Find the average temperature for those 10 days, and then print the number of days and the temperatures that were above average.
Example Dialog:
Welcome to the above average temperature tester program.
Please enter the temperature for day 1
97.0
Please enter the temperature for day 2
87.0
Please enter the temperature for day 3
85.0
Please enter the temperature for day 4
76.0
Please enter the temperature for day 5
83.0
Please enter the temperature for day 6
104.0
Please enter the temperature for day 7
78.0
Please enter the temperature for day 8
76.0
Please enter the temperature for day 9
90.0
Please enter the temperature for day 10
85.0
The average temperature was 86.1
The days that were above average were
Day 1 with 97
Day 2 with 87
Day 6 with 104
Day 9 with 90
DONE!
Explanation / Answer
TemparatureTest.java
import java.util.Scanner;
public class TemparatureTest {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.println("Welcome to the above average temperature tester program.");
double temp[] = new double[10];
for(int i=0; i<temp.length; i++){
System.out.println("Please enter the temperature for day "+(i+1)+": ");
temp[i] = scan.nextDouble();
}
double sumTemp = 0;
for(int i=0; i<temp.length; i++){
sumTemp = sumTemp + temp[i];
}
double averageTemp = sumTemp/temp.length;
System.out.println("The average temperature was "+averageTemp);
System.out.println("The days that were above average were: ");
for(int i=0; i<temp.length; i++){
if(averageTemp < temp[i]){
System.out.println("Day "+(i+1)+" with "+temp[i]);
}
}
System.out.println("DONE!");
}
}
