QUESTION
I try to run the method setForStatement
in this two lines:
cu.getNodesByType(ForStmt.class)
.forEach(Main::setForStatement);
I put hello-String in the different parts of the code to check which parts are works. But the method setForStatement doesn't run, because there are no the line "hello5" on the console:

Answered 2017-Dec-31 at 21:33I'm assuming you are using the library from http://javaparser.org/. Correct me if I'm wrong.
The reason that the method setForStatement(...)
isn't called is simply because cu.getNodesByType(ForStmt.class)
returns an empty list. You could easily verify this by adding the following line to your code:
System.out.println("For statements: " + cu.getNodesByType(ForStmt.class).size());
If you need help figuring out why it returns an empty list your really need to provide a mcve example.
