从同一目录中的另一个 class 访问公共 class 变量

Question

I've come across a java code in which the method aw_best_tour_index() of public class Utilities access the variable of the class InOut which is public . The variables of the class InOut are best_in_try and max_index . They've been called in the method like this:

final int[] values = InOut.best_in_try; and

final int l = InOut.maxindex; .

But when I compile this using javac in command prompt it shows the error "Cannot find symbol". What should be reason for this?

Answer 1

There could be multiple problems:

• Did you include InOut if it isn't in the same Java file
• Are the variables static
• If not, is InOut an instance of the class containing maxindex and best_in_try?
