通过其他方法将计算值存储在数组中

Question

I'm trying to make a program that calculates factorials from 0 to 19 in one method and storing those values in an array in another method (if that makes sense). This is my code so far, it works but I want to take the values in method long factorial (int number) in the void main(String[] args) method. But I'm having trouble executing this. I've tried changing System.out.println (factorial(counter)) to System.out.println (**x** [factorial(counter)]) but that failed. Sorry I'm new to programming and my English is not that good.

    for (int counter = 0; counter <= 20; counter++){

         System.out.println (factorial(counter));

If you need to store results in the x array, then just assign on each iteration:

for (int counter = 0; counter < size; counter++){
    x[counter] = factorial(counter);
    System.out.println(x[counter]);
}
