java - incompatible types error when providing a String to a method which requires a String -

I consider string values ​​as a string which accepts the string, although I am getting an "incompatible type" error. I I tried to codify an intensive value, to see what error I expect from:

found int; Required: java.lang.String

has changed the method for accepting the file, instead of errors:

string found; Required: java.io.file

Ergo, I'm feeding a string where the string should be. But I do not know where I'm going wrong. (And I have changed it to feed back the string and accept the string)

Any feedback is welcome in advance :)

  public should be zero string file reader (string filename)
