I am a newbie in java and need a method to remove any decimal from any length string and convert it without decimal. For example:

0.5555 should become 5555
0.045 should become 45
24.67 should become 2467
What is the simplest way to do this.

See if this helps.
private static String removeDecimals(String number) {
		
		String numberNoDots = number.replace(".", "");
		int index = -1;
		
		for (int i = 0; i < numberNoDots.length(); i++)
			if (numberNoDots.charAt(i) != '0') {
				index = i;
				break;
			}
		
		return numberNoDots.substring(index);
	}

All you need is the following, where 's' is the input string
s = "" + Integer.parseInt(s.replaceAll("\\.", ""));
