Java Tutorial : Java Array (Create, initialize, access an array)

ArrayDemo1.java

class ArrayDemo1
{
    public static void main(String[] args)
    {
        int[] intArray = new int[5];

        // initialize first element
        intArray[0] = 10;
        // initialize second element
        intArray[1] = 20;
        // and so forth
        intArray[2] = 30;
        intArray[3] = 40;
        intArray[4] = 50;

        int i = 0;
        for (int element : intArray)
        {
            System.out.println("Element at Index " + i + " : " + element);
            ++i;
        }
    }
}

Output

Element at Index 0 : 10
Element at Index 1 : 20
Element at Index 2 : 30
Element at Index 3 : 40
Element at Index 4 : 50

ArrayDemo2.java

public class ArrayDemo2
{
    public static void main(String[] args)
    {
        int[] intArray =
        { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 };

        int i = 0;
        for (int element : intArray)
        {
            System.out.println("Element at Index " + i + " : " + element);
            ++i;
        }

    }
}

Output
