Java Question (SOLVED) error: constructor File in class File cannot be applied to given types

[Johan Schoeman]

I am a bit lost here. I have opened the JAR of the below Library with JD-GUI and copied the code into notepad++. I want to modify the Java code and then recompile the code into a JAR. But when I use SLC (java 8) to compile it before making any changes to the code I get the following error:

error: constructor File in class File cannot be applied to given types

The original library works perfectly but after copying the code into a new Java project and compiling it with SLC it errors on this line:

 File file = new File(paramString1, paramString2);

File file = new File (String, String) is a valid constructor.

HtmlToPdf

Hello everybody, I've created this library that converts an html file (or string) to a pdf file programmatically. A couple of important notes: it only works on devices with SDK versions >= 21 and it cannot read files from the asset folder (you can either copy the file to the internal folder...

    }
    pdfPrint.print(paramWebView.createPrintDocumentAdapter(str1), file, paramString2);
  }
}

Towards the end of the code it also errors on this line although it is also a valid constructor:

File file = new File(paramString1);

Can anyone please point out what the reason for the error is when compiling it with SLC?

Solved using this:

java.io.File file = new java.io.File(paramString1);

It got confused with:
import anywheresoftware.b4a.objects.streams.File;
import java.io.File;
