Example : ArrayDemo

import java.io.*;
class ArrayDemo
{
int i;
int arr[]={1,2,3,4,5,6,7,8,9,10};
void result()
{
System.out.println("Array details \n");
for(i=0;i<10;i++)
{
System.out.print(arr[i] +"\t");
}
}
public static void main(String args[])
{
ArrayDemo d=new ArrayDemo();
d.result();
}
}

Average an Array of Values…

Example : Average

import java.io.*;
class Average
{
public static void main(String args[])
{
double nums[]={10.1,11.2,12.3,13.4,14.5};
double result=0;
int i;
for(i=0;i<5;i++)
result=result+nums[i];
System.out.println("Average is "+result/5);
}
}
