Java program to find the average of given numbers using arrays
You can read data from the user using scanner class.
- Using the nextInt() method of this class get the number of elements from the user.
- Create an empty array.
- Store the elements entered by the user in the array created above.
- Finally, Add all the elements in the array and divide the sub by the number of elements.
Example
import java.util.Scanner;
public class AverageUsingArrays {
public static void main(String args[]){
//Reading total no.of elements
Scanner sc = new Scanner(System.in);
System.out.println("Enter the number of elements/numbers");
int num = sc.nextInt();
//Creating an array
int[] myArray = new int[num];
//Read numbers from user and store it in an array
System.out.println("Enter the numbers one by one : ");
System.out.println("Press Enter button after each number : ");
for(int i =0; i<num; i++){
myArray[i] = sc.nextInt();
}
//Calculate the average
double average = 0;
for(int i =0; i<num; i++){
average = average + myArray[i];
}
average = average/num;
System.out.println("Average of given numbers :: "+average);
}
}Output
Enter the number of elements/numbers 5 Enter the numbers one by one : Press Enter button after each number : 55 66 55 55 66 Average of given numbers :: 59.4
