Java Tutorial : Java Array (String values)

ArrayDemo.java

class ArrayDemo
{
    public static void main(String[] args)
    {
        // declares an array of Strings and allocates memory for 10 Strings
        String[] strArray = new String[10];

        // initialize first element
        strArray[0] = "Apple";
        // initialize second element
        strArray[1] = "Ball";
        // and so forth
        strArray[2] = "Car";
        strArray[3] = "Dog";
        strArray[4] = "Eagle";
        strArray[5] = "Fox";
        strArray[6] = "Girl";
        strArray[7] = "Horse";
        strArray[8] = "Ink";
        strArray[9] = "Jack";

        System.out.println("Element at index 0: " + strArray[0]);
        System.out.println("Element at index 1: " + strArray[1]);
        System.out.println("Element at index 2: " + strArray[2]);
        System.out.println("Element at index 3: " + strArray[3]);
        System.out.println("Element at index 4: " + strArray[4]);
        System.out.println("Element at index 5: " + strArray[5]);
        System.out.println("Element at index 6: " + strArray[6]);
        System.out.println("Element at index 7: " + strArray[7]);
        System.out.println("Element at index 8: " + strArray[8]);
        System.out.println("Element at index 9: " + strArray[9]);

    }
}

Output

Element at index 0: Apple
Element at index 1: Ball
Element at index 2: Car
Element at index 3: Dog
Element at index 4: Eagle
Element at index 5: Fox
Element at index 6: Girl
Element at index 7: Horse
Element at index 8: Ink
Element at index 9: Jack

        System.out.println("Using For-each loop getting each element from the String Array\n");

        /*
         * Using For-each loop get all elements from strArray
         */
        int i=0;
        for (String value : strArray)
        {
            System.out.println("Element at index " +i+" : "+ value);
            ++i;
        }
    }
}

Output
