The IDE should tell the users if they make mistake during  entering condition;

Let's consider following dummy example:


public class Test {
    public static void main(String[] args) {
        List<User> users = new ArrayList<User>();
        users.add(new User("a",45));
        users.add(new User("b",8));

        for (User user : users) {
            if (user.age<=45) {
                System.out.println(user.age);
                System.out.println(user.name);
            }
        }
    }
}

Let's assume that by mistake i added following condition :user.age=8 instead of user.age==8
 and put it on the   if (user.age<=45) { line.

The current output during debug will become:
8
a
8
b

The expected result should be error box saying that i condition i added to the breakpoint in not valid.
