Run java function every hour

Question

I want to run a function every hour, to email users a hourly screenshot of their progress. I code set up to do so in a function called sendScreenshot()

How can I run

Answer 1

According to this article by Oracle, it's also possible to use the @Schedule annotation:

@Schedule(hour = "*")
public void doSomething() {
    System.out.println("hello world");
}

For example, seconds and minutes can have values 0-59, hours 0-23, months 1-12.

Further options are also described there.
