Java – Display Array Elements

Java – Program to display array elements

• Array consists more than one element.
• It is recommended to process multiple elements using loops.
• We use for() loop as we know the number of repetitions.

class Code {       public static void main(String[] args)       {                   int[] arr = {4, 2, 8, 9, 1, 6, 7, 5};                   System.out.println(“Array elements are : “);                   for (int i=0 ; i<=arr.length-1 ; i++)                   {                               System.out.println(arr[i]);                   }       } }

Java – Program to display default values of array

• As soon as memory allocated to array, all the locations initialized with default  values based on type of array
  • Int – 0
  • Double – 0.0
  • Char – blank
  • String or Object – null
  • Boolean – false

class Code {       public static void main(String[] args)       {                   int[] arr = new int[6];                   System.out.println(“Default values of Array : “);                   for (int i=0 ; i<=arr.length-1 ; i++)                   {                               System.out.println(arr[i]);                   }       } }

Default Values of Object type:

class Code {       public static void main(String[] args)       {                   Object[] arr = new Object[6];                   System.out.println(“Default values of Array : “);                   for (int i=0 ; i<=arr.length-1 ; i++)                   {                               System.out.println(arr[i]);                   }       } }
