But is it possible to write lamda greek letter in IntelliJ IDEA or generally in any editor?

Answer 1

This is all about your keyboard and OS, and not specific to Intellij IDEA. You can create one by copy and pasting, which is pretty easy. If you want to insert it directly then use the way of typing special characters specific to your platform (Windows, Mac, Linux, ...).

• Double click or drag drop to input.<\/li>
• Then select Greek from the "flag" menu at the top right of the screen and type.<\/li><\/ul>

  There are also some suggestions on the Wikipedia article on entering special characters<\/a> , though IntelliJ may intercept some of these.

Answer 2

You can express any Unicode character anywhere in Java source code via the \? form. It is not just for String<\/code> s and char<\/code> s. (For characters outside the BMP, you need two of those, forming a surrogate pair.) Inasmuch as there sometimes are multiple characters with similar glyphs, Unicode escapes have the advantage of being totally unambiguous.
