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 Netbean 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.

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

double result = 0;

int l;



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



Output – Average of an array of Integers

The output of the above program is given below.

Average is 12.299999999999999
