How would I use printf() and a String array of inputed words to print out within a box of asterisks

In this format where 'Nivla' would be within a String List, and input is available to be formatted by the user.

************
*   Nivla  *
************

Also, the box would increase in size with the lines of the string array. E.g. ["Nivla is" , "not intelligent"];

**********************
*      Nivla is      *
*   not intelligent  *
**********************

Also, I'm having trouble centering the string around the center like above.

The code I'm current using is:

public void run() {
        Scanner s = new Scanner(System.in);
        ArrayList<String> inputs = new ArrayList<>();
        String input;
        do {
            input = s.nextLine();
            inputs.add(input);
        } while(!input.equals(""));
        printBox(inputs);
    }

    public void printBox(ArrayList inputs) {
        for (int i = 0; i < inputs.size(); i++) {
            System.out.printf("*\t%s\t*\n", inputs.get(i));
        }
    }

Is there any way to solve my issue?

You need to make the amount of spaces dependent on the length of the longest input instead of just printing tabs on each side. You should also add a padding parameter in your printBox method to specify how many spaces to put on each side of the word.

Here is one possible solution that works pretty decently:

    int max = 0;
int padding = 10;
public void run() {
Scanner s = new Scanner(System.in);
ArrayList<String> inputs = new ArrayList<>();
String input;
do {
input = s.nextLine();
inputs.add(input);
max = Math.max(max, input.length());
} while(!input.equals(""));
printBox(inputs, padding);
}
public void printBox(ArrayList inputs, int padding) {
printStars();
// go to size - 1 because the last input is always ""
for (int i = 0; i < inputs.size() - 1; i++) {
int len = ((String)inputs.get(i)).length();
int frontPad = (max + len)/2 + padding;
// need to round or else sometimes the padding will be one too short
int backPad = padding + (int)Math.round(((max - len)/2.0));
System.out.printf("*%" + frontPad + "s%" + backPad + "s\n", inputs.get(i), "*");
}
printStars();
}
private void printStars() {
for (int i = 0; i <= max + padding*2; i++) {
System.out.print("*");
}
System.out.println();
}
