Using recursion to create a one line number pattern

Write a recursive method that prints out a numeric sequence. printSequence(4) prints 1 2 3 4 3 2 1

public class Practice {
    public static void main(String[] args){
        printSequence(4);
    }

    public static void printSequence(int n){
        System.out.print(n);

        if(n>1){
            printSequence(n-1);
        }

        System.out.print(n);
    }
}

My code is there, and the output is pretty obvious, but it's 43211234. My desired output is 1234321, and I'm not sure how to get there. Unless I can use two methods, but only call one in main, I don't think I can use two methods. Does anyone know how I can get my desired output: 1 2 3 4 3 2 1 recursively, and only using one method?
