IDENT is an identifier... it's probably a variable initialization that wasn't done properly.
Often, the compiler (or pre-processor) will wait until the end to complain about an error.

Let me take a wild guess (not wild at all, as this happens every single time): it highlights the last line of your second tab. I don't even need clarification, this is almost certainly correct.

The problem probably isn't even in that tab... where were you editing last? It helps to make small changes, then run the code, then look for errors where the small changes took place. Perhaps comment out previous edits until the code runs clean. An easier method is to paste your code into a Java IDE, such as Eclipse... as this will highlight your syntax errors immediately (as long as it doesn't have something more worrisome to report).

Hints:
- Use Ctrl+T (or Edit > Auto-Format) on each tab to correctly indent code, it often helps spotting missing braces.
- If you click on a closing or opening brace, the matching one is highlighted. It helps spotting a missing brace.
That's for { } non-matching, a common cause of errors.

But your error is slightly different. I can reproduce it by taking a valid line, like:
h3 = new Heart(250f, 220f, 100f, #800000, #AA5555);
and adding a second closing brace at the end (before the semi-colon), for example.
Perhaps you typed accidentally the wrong number of closing braces (can be easy in expressions like ((a + b) * c + sin(x))) for example).
