    Default Doubling Letter in a String -- Stuck on Code

    Hey guys! So I'm asked to make a piece of code that takes a string of text that a user inputs and print to the console the same string but with each letter doubled and each '!' tripled.

    Example: hey, guys! ---> hheeyy, gguuyyss!!!

    I have made the code below so far, and it works, however I need to be able to triple the '!' while having commas and other special characters remain at 1! I have tried adding more if-statements but it seems to only break the output even more. Any help would be appreciated. Thank you!!!

    So far, I will input "hey, guys!" and receive "hheeyy, gguuyyss!" (I need the '!' tripled without doubling the comma.

    import java.util.Scanner;
    public class DoubleLetters {
    	public static void main (String[] args) {
    		Scanner scan = new Scanner(System.in);
    		System.out.println("Please type a sentence:");
    		String input = scan.nextLine();
    		int length = input.length();
    		String newString = "";
    		for(int j = 0; j < length; j++) {
    			        newString = newString + input.charAt(j) + input.charAt(j);
    				newString = newString + input.charAt(j);

    --- Update ---

    I've been thinking and I think the only way I can do this is with another if-statement. I'm not sure if I should put it right after the first if-statement or after the else

    Yes, you would need add another if to detect the !
