How to check whether it's matching "if" using "else"

[Andrew liu]

Recently, i meet a problem. According to our coding rule, we should use keyword "else" to match keyword "if". I want to check that.
Now, i used Stack to check whether the program has the mismatching. But i cannot accurately indicate where the mismatching occus.
Such as:
1 if (true) {
2 // something omitted...
3 } else {
4 if {
5 // something omitted...
6 }
7 }

In line 4, the mismatching occurs. But how can i indicate it?

JAVA law says
that an else clause belongs to the innermost if statement to which it might
possibly belong (in other words, the closest preceding if that doesn't have an else).
Think about this law and then try to figure out where in your code the mismatch occurs
