In this program, we need to print the elements of the array in reverse order that is; the last element should be displayed first, followed by second last element and so on.

Above array in reversed order:

Algorithm

  • STEP 1: START
  • STEP 2: INITIALIZE arr[] = {1, 2, 3, 4, 5}
  • STEP 3: PRINT "Original Array:"
  • STEP 4: REPEAT STEP 5 for(i=0; i<arr.length ; i++)
  • STEP 5: PRINT arr[i]
  • STEP 6: PRINT "Array in reverse order"
  • STEP 7: REPEAT STEP 8 for(i= arr.length-1; i>=0; i--)
  • STEP 8: PRINT a[i]
  • STEP 9: END

Program:

public class ReverseArray {  
    public static void main(String[] args) {  
        //Initialize array  
        int [] arr = new int [] {1, 2, 3, 4, 5};  
        System.out.println("Original array: ");  
        for (int i = 0; i < arr.length; i++) {  
            System.out.print(arr[i] + " ");  
        }  
        System.out.println();  
        System.out.println("Array in reverse order: ");  
        //Loop through the array in reverse order  
        for (int i = arr.length-1; i >= 0; i--) {  
            System.out.print(arr[i] + " ");  
        }  
    }  
}

Output:

 Original array: 
1	2   3   4   5
Array in reverse order:
5    4   3   2   1
