Java program to find the average of n numbers

This Java program finds the average on n numbers using command line arguments. The program uses a try catch statement to read the arguments form the command line. Each arguments are stored to the array a[] using a while loop. Then the program uses another while loop to calculate the sum of all the elements in the array a[] and it will be stored in the variable sum. The statement avg=sum/n; outside the while loop calculates the average and it will be displayed in the output screen.

public class Average

{

public static void main(String s[]) throws Exception

{

int a[]=new int[10];

int i=0,n,sum=0,avg;

n=s.length;

try

{

while(i<n)

{

a[i]=Integer.parseInt(s[i]); //taking values from command line

i++;

}

}

catch(Exception e)

{

System.out.println("Error");

}

n=i;

i=0;

while(i<n)

{

sum=sum+a[i];

i++;

}

avg=sum/n;

System.out.println("Average is: "+avg);

}

}
