Java – Access array elements

Access Array elements

• Array is automatically initializes with default values.
• Default values depend on type of array.
• We can process array elements using their index

class Demo 
{
	public static void main(String[] args) 
	{
		int arr[ ] = new int[5];
		System.out.println("Array elements are : " );
		for (int i=0 ; i<arr.length ; i++)
		{
			System.out.println(arr[i]);
		}
	}
}

• If the array is of type String, the default value is null.
• String is a class(object).
• Object stores memory address, hence it is called pointer variable.
• Default pointer variable is null.

class Demo 
{
	public static void main(String[] args) 
	{
		String arr[ ] = new String[5];
		System.out.println("Array elements are : " );
		for (int i=0 ; i<arr.length ; i++)
		{
			System.out.println(arr[i]);
		}
	}
}
