Answer:
Because people have it written down now how it should be said and now call it a rule.
Explanation:

We are being asked to declare a variable, thus, we can use "PrintWriter" that is suitable for referring to an object that provides methods for writing to a text file.
On how to use it, we can define it such as
Output.printIn ="hi";
output.close;
