Question

How to count lines of Java code using IntelliJ IDEA?

Answer 1

In the past I have used the excellently named MetricsReloaded plugin to get this information.

You can install it from the JetBrains repository.

Once installed, access via: Analyze -> Calculate Metrics...

Answer 2

You can to use Count Lines of Code (CLOC)

On Settings -> External Tools add a new tool

• Name: Count Lines of Code
• Group: Statistics
• Program: path/to/cloc
• Parameters: $ProjectFileDir$ or $FileParentDir$

Answer 3

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.
