this will help I try to print letter D on console, but I couldn't help the code is longer than my expectation. Could you help me.... there are another way to reduce this code? Thank you. This is my code: , Helper methods simply your code a lot:
public static void main(String[] args) {
    printAsterisks(11, true);
    printAsterisks(13, true);
    for(int i = 6; i < 10; i++){
    for(int i = 10; i > 5; i--){
    printAsterisks(13, true);
    printAsterisks(11, true);

static void printSpaced(int spaces){
    printAsterisks(4, false);
    for(int i = 0; i < spaces; i++){
        System.out.print(" ");
    printAsterisks(4, true);

static void printAsterisks(int n, boolean newLine){
    for(int i = 0; i < n; i++){

I think the issue was by ths following , Yes, I was wrong, and missed that tested method was not just fastLoop calls:
  def loop(): BigInt =
    if (n > 92) loop(n - 91, 4660046610375530309L, 7540113804746346429L)
    else fastLoop(n)
    public BigInteger loop() {
        return n > 92 ?
                loop(n - 91, BigInteger.valueOf(4660046610375530309L), BigInteger.valueOf(7540113804746346429L)) :
                BigInteger.valueOf(fastLoop(n, 0, 1));
