Write a statement that declares a PrintWriter reference variable named output and initializes it to a reference to a newly created PrintWriter object associated with a file named "output. txt".

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.

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
