      public static Comic[] createComics() {
        Comic[] comics = new Comic[] {
                new Comic("978-0785199618", "Spider-Man:Miles Morales", 112, 0.72),
                new Comic("978-0785190219", "Ms.Marvel:No Normal", 120, 0.80),
                new Comic("978-0785198956", "Secret Wars", 312, 1.75),
                new Comic("978-0785156598", "Infinity Gauntlet", 256, 1.42)
        };
        return comics;
    }

I am fairly new to java and right now I am at a roadblock for displaying that message using joptionpane. I don't want to hardcode it exactly but I have zero clue on how to format my message to the one similar to the image. I'm assuming I have to use String.format but I couldn't find any resources that helps me. The code above is the method for the fake database of comics.

String.format("%-25s | %-35s | %-6s | %-1s | %s %n------------------------------------------------------------------------------------------------", "ISBN-13", "Title", "Pages", "Price/Day", "Deposit"); This is all I could come up with thus far

./run java

var fmt = "%-25s | %-35s | %-6s | %-1s | %s%n";
var sb= new StringBuilder();
sb.append(String.format(fmt, "ISBN-13", "Title", "Pages", "Price/Day", "Deposit"));
sb.append("------------------------------------------------------------------------------------------------\n");
for (int i= 0; i< 5; i++) {
    sb.append(String.format(fmt, "isbn " + i, "title"+i, "pages"+i, "price day"+i, "deposit"+i));
}
System.out.println(sb.toString());
