how can i remove the error

[claxx1890]

hello everyone

so i have a problem with a project in java .. the problem is : Error: Main method not found in class e.mersul.trenurilor.ManagerListaTrenuri, please define the main method as:
public static void main(String[] args) and the code of java , a part of it just a class is this:

and this line of code make me crazy .. please help me if everyone knows what is the problem, and please forgive me for my language, thanks

I just did "^F main" but indeed, no sign of "main" in the vicinity; the compiler was right (as always).

kind regards,
