Write a
“NumberAboveAverage” class
Program Plan:
“NumberAboveAverage.java”:
- • Define “NumberAboveAverage” class.
- ○ Define main function.
- ■ Declare an array “temperature” in “double” base type.
- ■ Create an object for scanner class.
- ■ Display prompt statement.
- ■ Read ten temperature from user using “for” loop.
- • Display prompt statement for each temperature.
- • Read temperature one by one from user.
- ■ Initializes total temperature “total_temp” to “0.0”.
- ■ Compute sum of all temperature using “for” loop.
- • The sum is computed by using “total_temp += temperature[i];”
- ■ The average temperature is computed by using “total_temp/10” and it is stored to a variable “tempAverage”.
- ■ Display average temperature.
- ■ Initializes the day count “dayCount” to “0”.
- ■ Using “for” loop, compute which day has above average.
- • If temperature is greater than average temperature, then increment the day count.
- • Display the day which has above average temperature.
- ■ Finally display total number of days has above temperature.
- ○ Define main function.
The below java program is used to counts the number of days that the temperature is above the average of temperature.
Explanation of Solution
Program:
Filename: “NumberAboveAverage.java”
//Import required package
import java.util.Scanner;
//Define "NumberAboveAverage" class
public class NumberAboveAverage
{
//Define main function
public static void main(String[] args)
{
//Declare an array for temperature
double[] temperature = new double[10];
//Create object for scanner class
Scanner reader = new Scanner(System.in);
//Display prompt statement
System.out.println("Please enter the values of ten temperature");
//Read ten temperatures from user using "for" loop
for(int i = 0; i < 10; i++)
{
//Prompt statement for temperature
System.out.print("Enter temperature for Day " + i + " is: ");
//Read temperature one by one from user
temperature[i] = reader.nextDouble();
}
//Initializes total temperature to "0".
double total_temp = 0.0;
//Compute sum of all temperature using "for" loop
for(int i = 0; i < 10; i++)
{
total_temp += temperature[i];
}
//Compute the average temperature to "0"
double tempAverage = total_temp/10;
//Display average temperature
System.out.println("The average temperature is: " + tempAverage);
//Initializes the day count to "0"
int dayCount = 0;
//Using "for" loop, compute which day has above average
for(int i = 0; i < 10; i++)
{
/* If temperature is greater than average temperature, then */
if( temperature[i] > tempAverage)
{
//Increment the day count
dayCount++;
//Display the day which has above average temperature
System.out.println("Day " + i + " had temperature " + temperature[i] + " which was above average");
}
}
//Finally display total number of days has above temperature
System.out.println("The number of days with a temperature above average is: " + dayCount);
}
}
Output:
Please enter the values of ten temperature
Enter temperature for Day 0 is: 10
Enter temperature for Day 1 is: 40
Enter temperature for Day 2 is: 15
Enter temperature for Day 3 is: 80
Enter temperature for Day 4 is: 42
Enter temperature for Day 5 is: 28
Enter temperature for Day 6 is: 48
Enter temperature for Day 7 is: 12
Enter temperature for Day 8 is: 30
Enter temperature for Day 9 is: 84
The average temperature is: 38.9
Day 1 had temperature 40.0 which was above average
Day 3 had temperature 80.0 which was above average
Day 4 had temperature 42.0 which was above average
Day 6 had temperature 48.0 which was above average
Day 9 had temperature 84.0 which was above average
The number of days with a temperature above average is: 5
