How to disable a method in java @component class?

I am using java 8 with spring boot
I have a class

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
@Component
class Sample{
    @Scheduled(cron = "00 00 00 * * *")
    public void print(){
        System.out.println("Hello World!");
    }
}

This method is will be invoked daily at 00:00:000 AM
Now for a time beeing I want to stop invoking that method.
One way we can comment the method.
Is there any better way to do that?
Like @Disabled in junit.

I agree on the approaches mentioned above but there is an another alternative as well like the below,

To implement a Spring "condition" interface which overrides the matches method with a return type of boolean value (i.e., You can write your own custom logic with boolean return).

then, use the Annotation @Conditional(yourconditionclassname.class) on the @Component/@Configuration/@bean. This way, the scheduled method executes only when the condition class returns true.

Hope this helps as an alternative approach.

You can to use application.yml for feature flags in Spring Boot apps. This file usually defines the configuration of an application and simultaneously can be a perfect place for feature toggle. Based on a flag you can enable/disable the funcionality.

feature-flags:
    is-xyz-method-enabled :true

inside the method just simply do a check for this property.

  @Value("${is-xyz-method-enabled}")
  private boolean isEnabled;

  @Scheduled()
  public void xyz() {
    if(isEnabled) {
 
    }
  }

Add condition on component like

@ConditionalOnProperty(name="schdularEnabled", value="true")

Then you can use application.yml with environment variables to toggle the shchedular
