How do I display a word diagonally in Java?

How do I display a word diagonally in Java?

I am trying to make a program that accepts a word then displays the word
diagonally. So far I've only gotten it to display vertically.
The scanner accepts "zip", then outputs:
z
i
p
How do i make it go like this:
z
i
p
Here is my code:
import java.util.Scanner;
public class exercise_4
{
public static void main(String [] args)
{
Scanner scan = new Scanner(System.in);
System.out.println("Please enter your words");
String word = scan.nextLine();
for(char ch: word.toCharArray())
{
System.out.println(ch);
}
}
}
