Program to compute Average of an array of integers

The program to compute average of an array of integers is a simple program to demonstrate the usage of arrays.The program is intended for beginners of Java programming language.

We are using JDK 8u111 with Netbeans IDE 8.2 installed on a Windows 7 64-bit PC to compile and run the program. You may alternatively install JDK and compile and run the program from windows command line.

Problem Definition

To compute the average of integers stored in an array, first, we receive the user input values for an array. The next step sums the array of integers and divides by the total number of integers. This will give the average values and you can now display the results.

    public static void main(String args[]){

    double num[]={10.1,11.2,12.3,13.4,14.5};

    double result = 0;

    int l;

    for(l=0;l<5;l++)

        result=result+num[l];

        System.out.println("Average is " + result/5);
 
    }

}

Output

Average is 12.299999999999999
