Eclipse calculates the number of lines of code for the entire project

Today, I want to count the completion of the project.CodeNumber of rows. I would like to manually calculate it and find it unreliable. Then I find that the statistics can be as follows:

1.Search-> File

2. \ n refers to the statistics of line breaks, because there are several lines with several line breaks, so it is equivalent to the number of lines.

Filenamepattern is selected based on your needs.

Remember to check "Regular Expression ".

3. Now, click search ~~~

(⊙ O ⊙)91,318 million lines ............................................................
