  • The subject will always be the same? Only the amount will change? Commented Aug 17, 2017 at 14:38

If you're sure the subject will never change except for the amount, you should use the substringBetween(open, close) method of the String class. You can use the ':' character as open tag and 'USD' as close tag.

Then, you can use the trim() method of the String class to remove any leading or trailing white space characters.

Here's the code:

String amountStr = subject.substringBetween(':', 'USD').trim();
