How to replace/delete comments or lines starts with particular word in Android studio?

Issue

I want to delete all comments in an android project, all the comments start with // or any other specific characters?

Solution

In android studio, right-click on the project and select Replace in files, a new window pop up

1 in the first search field tape in this ^\s+//.*$

2 in the second search field, keep it empty if you just want to delete all the lines that start with //

3 now hit replace all button.

if you want to delete other lines that start with different characters, example @ the expression should be like this ^\s+@.*$
