Java Reverse integer array

In this tutorial, you will learn how to reverse integer array. Here, we have created a method to reverse an array which has been passed as a parameter and returns a new array with all the elements in reverse order. In the main method, we have allowed the user to enter numbers and invoked the method.

Example:

import java.util.*;
class ReverseArray{
public static int [] reverse (int a[]){
for ( int i = 0 ; i < a.length/2 ; i++ ){
int temp = a[i] ;
a[i] = a[a.length-i-1] ;
a[a.length-i-1] = temp ;

}
return a;
}

public static void main(String[] args) 
{
int a[]=new int[5];
Scanner input=new Scanner(System.in);
System.out.println("Enter five array elements: ");
for(int i=0;i<a.length;i++){
a[i]=input.nextInt();
}
int array[]=reverse(a);
System.out.println("Array In Reverse Order: ");
for(int i=0;i<array.length;i++){
System.out.println(array[i]);
}
}
}

Output:

Enter five array elements:
3
5
6
2
4
Array In Reverse Order:
4
2
6
5
3
