import java.util.Scanner;
class Main{
public static void main(String args[]){
Scanner input= new Scanner (System.in);
System.out.println("Enter size");
int my_array = input.nextInt();
System.out.println("Enter numbers to reverse");
int[] intArray =new int[my_array];
for(int i=0;i<intArray.length;i++)
{
intArray[i]=input.nextInt();
}
for(int i=intArray.length-1;i>=0;i--)
System.out.println(intArray[i]);
}
}
//Is this your expected output?

There were multiple errors in your program u need to use the primitive datatype for the declaration not the wrapper class
And you need to loop over the inputs otherwise it will take default values that is 0
