Java Array Simple Program Example

The following program, ArrayDemo, creates an array of integers, puts some values in the array, and prints each value to standard output.

public class ArrayBasics {
        public static void main(String[] args) {
                // declares an array of integers
            int[] anArray;
   
           // allocates memory for 10 integers
            anArray = new int[10];
            
            // initialize first element
            anArray[0] = 100;
            // initialize second element
            anArray[1] = 200;
            // and so forth
            anArray[2] = 300;
            anArray[3] = 400;
            anArray[4] = 500;
            anArray[5] = 600;
            anArray[6] = 700;
            anArray[7] = 800;
            anArray[8] = 900;
            anArray[9] = 1000;
 
            for (int i = 0; i < anArray.length; i++) {
                 System.out.println("Element at index " + i + ": " +anArray[i]);
            }
       }
}

Output:

Element at index 0: 100
Element at index 1: 200
Element at index 2: 300
Element at index 3: 400
Element at index 4: 500
Element at index 5: 600
Element at index 6: 700
Element at index 7: 800
Element at index 8: 900
Element at index 9: 1000
