How to add padding to left and right of a string in Java

Question

I want to add padding to left and right of my string and print something like:

|          WELCOME TO THE GAME          |

I am trying this:

System.out.printf("|%15s%20s|%n",header,"");

and the output is:

|WELCOME TO THE GAME                    |

I have 2 questions here:

1. Any better way to do padding both left and right of my keyword without actually using an empty string?
2. What would be the right formatting to get the desired output?

Answer 1

change it to 30, 10

System.out.printf("|%30s%10s|%n",header,"");

it's output

|           WELCOME TO THE GAME          |
