Java构建相互依赖的事件链

Question

I hava a set of methods of type boolean which are settings things up. Each method return true if busines logic was successfully executed and false if anything went wrong. I would like to break chain at first fail .

Are there any good practicies?

ATM I am doing something like this:

if (taskIsDone(task) && taskGenerateReport(task) && taskReportIsDone(task) && taskProcessReport(task)){
    log.info("Processing of task {} is done", task.getName());
} else {
    log.error("Task {} finished with error", task.getName());
}

Something like this works in my dev env but if scenario when for any reason order of methods would change logic like this is useless.

Could anyone give me a hint how to make it right?

Answer 1

As the other people said, the order of execution is from the left to the right.

In your case, I would call task.isDone() or task.generateReport() and so on, as it's related to the task which is in your case probably a domain object.
