printing - Writing a word in a rhombus/diamond shape in Java

Question

I have to write a program that asks a word and then prints it in a rhombus/diamond shape, like this:

Word: Hello
H
He
Hel
Hell
Hello
 ello
  llo
   lo
    o

I tried something but I really could use some help if someone could, I tried something like this:

import java.util.Scanner;

public class Rhombus {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        System.out.print("Word: ");
        String word = sc.nextLine();
        int wordLength = word.length();

        for (int i = 0; i < wordLength; i++) {
            System.out.println(word.substring(0, i));

        }
    }
}

Here you are:

public static void main(String[] args) {
    printRhombusText("yolobird");
}

public static void printRhombusText(String s) {
    // top part
    for (int i = 1; i <= s.length(); ++i) {
        System.out.println(s.substring(0, i));
    }
    // bottom part
    for (int i = 1; i <= s.length(); ++i) {
        // print out the space
        for (int y = i; y > 0; --y) {
            System.out.print(" ");
        }
        System.out.println(s.substring(i));
    }
}

output:

y
yo
yol
yolo
yolob
yolobi
yolobir
yolobird
 olobird
  lobird
   obird
    bird
     ird
      rd
       d
        

Want to add user input? Here:

public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    do {
        System.out.print("Input your text: ");
        String input = scanner.nextLine();
        printRhombusText(input);
        scanner.reset();
        System.out.print("You want to do one more? (y/n): ");
    } while (scanner.nextLine().trim().equals("y"));
}

output:

Input your text: kiet
k
ki
kie
kiet
 iet
  et
   t
    
You want to do one more? (y/n): y
Input your text: ahihi
a
ah
ahi
ahih
ahihi
 hihi
  ihi
   hi
    i
     
You want to do one more? (y/n): n
