Question

How to count lines of Java code using IntelliJ IDEA?

Answer 1

To find all including empty lines of code try @Neil's solution:

Open Find in Path (Ctrl+Shift+F)

Search for the following regular expression: \n'

For lines with at least one character use following expression:

(.+)\n

For lines with at least one word character or digit use following expression:

`(.*)([\w\d]+)(.*)\n`

Notice: But the last line of file is just counted if you have a line break after it.
