Java – For Each Loop – Ameerpet Technologies

Java – Program to display array elements using for each loop

For-each loop is used to process Array or Collection elements easily.
For-each loop process elements from start to end without using index.
For-each loop process elements only in forward direction.

class Code
{
      public static void main(String[] args)
      {
                  int[] arr = {4, 2, 8, 9, 1, 6, 7, 5};
                  System.out.println(“Array elements using for-each loop : “);
                  for (int x : arr)
                  {
                              System.out.println(x);
                  }
      }
}

Java – Replace the first element and last element with 10

class Code
{
      public static void main(String[] args)
      {
                  int[] arr = {4, 2, 8, 9, 1, 6, 7, 5};
                  arr[0] = 10;
                  arr[arr.length-1] = 10;
                  System.out.println(“Array elements : “);
                  for (int x : arr)
                  {
                              System.out.println(x);
                  }
      }
}
