Java: Errors when working with variables

The main rule: a variable must be declared before it is used. If you do this later, the program simply will not work.

System.out.print(greeting);
greeting = "Father!";

The launch of the program the above ends with an error:

Error: java: cannot find symbol
symbol: variable greeting

This error means that the code uses a variable that is not defined. And in the error itself they say this directly: variable greeting. In addition to the wrong order of definition, in Java there are commonplace typos, both when using a variable and when it is declared.

The number of such errors is reduced by using a properly configured editor. This editor highlights the names that are used without the announcement and warns of possible problems.

Instructions

Find an undeclared variable in the program and declare it assigning to it the value of "Dragon";
