Answer:
PrintWriter variable = new PrintWriter("output.txt");
Explanation:
There are two ways of declaring a reference variable in programming.
One way is
Reference Variable-name = new Reference ("some texts here");
While the other is
Reference Variable-name;
Variable-name = new Reference ("some texts here");
Both ways are valid ways of reference variable declaration.
In the question above, the reference is PrintWriter, it points to output.txt and the question says "write a single statement";
Hence, we make use of
PrintWriter variable = new PrintWriter("output.txt");
A reference variable is declared to be of a specific type and that type can never be changed.
