Echoing Integers Using an Array with Java

I'm working to create a program that takes in 5 integers via user input, separated by spaces on the same line. From there I need to assign these integers to an array and then echo the array back.
Should be pretty straightforward, but I am having a tough time where my echo back is not inserting spaces between the integers i.e, the users input is {1 2 3 4 5} and the result is 12345, which should ideally be {1 2 3 4 5}.
This is my first opportunity to play with arrays, so any assistance would be helpful!
Below is the code I have written thus far:
package echo5ints;
import java.util.Scanner;
/**
*
* @author laure
*/
public class U7D1_Echo5Ints {
/**
* @param args the command line arguments
*/
public static void main(String args) {
int i =0;
int arr=new int[5];
Scanner input = new Scanner(System.in);
System.out.print("Please enter 5 numbers: ");
String line = input.nextLine();
Scanner numbers = new Scanner(line);
for(i=0;i<5;i++)
arr[i]=numbers.nextInt();
System.out.println("These were the 5 numbers entered: " + arr[0] + arr[1] + arr[2] + arr[3] + arr[4] );
}
}

try using split instead and printf
System.out.print("Please enter 5 numbers: ");
String line = input.nextLine();
String arr = line.split (" ");
System.out.printf("These were the 5 numbers entered: %s %s %s %s %s",
arr[0], arr[1], arr[2], arr[3], arr[4] );

Printf only print what appears inside quotes or the values held by variables.
SO your print line should be
System.out.println("These were the 5 numbers entered: " + arr[0] +" "+ arr[1] +" " + arr[2] +" " + arr[3] +" " + arr[4] );
