Printing the return statement?

So I'm doing a project in which I need to make a table of values, one column of x and the other column of x! I know how to make the factorial program (and it worked before I put in the print statements), however when I'm trying to print the return statements, it's not working. Can someone please help me? public static double myexp (double n) { System.out.println(n); if (n<=1) { return 1; } else { System.out.print("\t"); //return n*myexp(n-1); System.out.print(return n*myexp(n-1)); } }
