System.out.println("My favorite type of pie is " + pie.toString().toLowerCase().replaceAll("_", " ").replaceAll("2", "").replaceAll("3", "").replaceAll("4", "") + ".");
Example code ripped up, but how would I make that '.replaceAll("number", "")' replace all numbers less than or equal to 4 with a more simple code? Creating a new .replaceAll 3 times is redundant. If I do...:
double number[] = {1, 2, 3, 4};
pie.toString().toLowerCase().replaceAll("_", " ").replaceAll(number.toString(), "") + ".");
...I'll get a nasty error.
Here's the error...
