Learn Java Programming Language Part - III

Array is a collection of similar type of elements that have contiguous memory location. Java Array is an object the contains elements of similar data type. It is a data structure where we store similar elements. We can store only fixed set of elements in a java array.

                                     Single Dimensional Array Example

{
   public static void main(String args[])
   {
           int a[] = new int[3];
           a[0] = 20;
           a[1] = 40;
           a[2] = 60;
           for(int i=0;i<a.length;i++)
           {
               System.out.println(a[i]);
           }
    }
}
