Given an array[]={1,2,3,4,5,6,7,8,9} if we want to print it in a reverse order such that last entry of array[] appears to be first and second last to be second and so on,Hence we can serve this purpose with the help of this program. 

Original Array:
Array1[]={1,2,3,4,5,6,7,8,9}
RevArray[]={9,8,7,6,5,4,3,2,1}

In this topic we are going to take Three Examples. In Example-1 we will take Static Inputs(Pre-Defined Inputs). And in Example-2 we will take User Defined Inputs.

Algorithm/Program Explanation

  1. Start
  2. Define and Initialize array
    • array[]={data};
  3. Define for Loop
    • for (int i = 0; i < array.length; i++)
    • Print original array.
  4. Define for loop
    • for (int i = array.length-1; i>=0; i–)
    • Print array in reverse order
  5. End

Example-1 Taking Static Inputs

/*
Java Program to Print Array in Reverse Order */
import java.util.*;
public class reversearray{
 public static void main(String args[]) {
  int array[] = {1, 2, 3, 4, 5, 6, 7, 8, 9};
  System.out.println("Original Array:");
  for (int i = 0; i < array.length; i++) {
   System.out.print(array[i] + "|");
  }
  System.out.println();
  System.out.println("Array in reverse order");
  for (int i = array.length-1; i>=0; i--) {
   System.out.print(array[i] + "|");
  }
 }
}

Output:
Original Array:
1|2|3|4|5|6|7|8|9|
Array in reverse order
9|8|7|6|5|4|3|2|1|

Example 2- Taking User Defined Inputs

/*
Java Program to Print Array in Reverse Order */
import java.util.*;
public class reversearray{
 public static void main(String args[]) {
  System.out.println("Enter the Size of Element:");
  Scanner sc=new Scanner(System.in);
  int n;
  n=sc.nextInt();
  int array[] = new int[n];
  System.out.println("Enter The Elements in Arrays:");
  for(int  i=0;i<array.length;i++){
   array[i]=sc.nextInt();
  }
  System.out.println("Original Array:");
  for (int i = 0; i < array.length; i++) {
   System.out.print(array[i] + "|");
  }
  System.out.println();
  System.out.println("Array in reverse order");
  for (int i = array.length-1; i>=0; i--) {
   System.out.print(array[i] + "|");
  }
 }
}

Question asked in this Topic:
