Declarations

Description Declarations of instance variables, methods, and other class-level declarations are used to provide control over the class. The example shows a declaration of an instance variable count and a method called transform. The combination translates every odd numbered word to upper case.

		out.print(s.toUpperCase());
	}
}

#

public class test {

	String[] words = {
	#for "//word"#
		"# transform(context.evalString("."), out); #",
	#end#
	};
