elements Print array elements in reverse order in java​

Answer 1

Answer:

Explanation:Program to print the elements of an array in reverse order

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.

Program to print the elements of an array in reverse order

Above array in reversed order:

Program to print the elements of an array in reverse 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
