PrintWriter out = new PrintWriter (new File ("myOutput. txt"));

Explanation:

PrintWriter object is used to create an abstraction to a File for writing purpose.

PrintWriter constructor with File object input takes one of the two forms:

PrintWriter (File) PrintWriter (File, String).

Among the given options, option 4 corresponds to PrintWriter object creation using the first version of PrintWriter constructor.

So the valid option that declares a PrintWriter object for an output file 'myOutput. txt' is:

PrintWriter out = new PrintWriter (new File ("myOutput. txt"));
