I can't print my array with int a = arr.length

Question

If I put a number instead "a" my sister.out.println(arr[a]);
It works perfectly but if I use arr[a] it send a wrong

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String text = scanner.nextLine();
char[] arr = text.toCharArray();

int a = 0 ;
int x = arr.length;

while (a <= x){

System.out.println(arr[a]);
a++;
}

}
}

Answer 1

Do you have a question? I don't see a question or problem here.

Answer 2

Yes, Ipang is right.

You probably want < instead of <=.
while (a < x){

System.out.println(arr[a]);
a++;
}

Answer 3

Sorry, the title is I can't instead I can

Answer 4

Your while loop should run while <a> less than <x>, not while <a> less than or equal to <x>.

while( a < x )
