Lambda that does absolutely nothing
I needed to have a lambda expression of the functional interface Runnable that did nothing. I used to have a method
private void doNothing(){
//Do nothing
}
and then use this::doNothing. But I've found an even shorter way to do this.
For Runnable interface you should have something like that:
Runnable runnable = () -> {};
Where:
-
()because run method doesn't receive args -
{}body of run method which in this case is empty
After that, you can call the method
runnable.run();
The lambda expression I use now is:
() -> {}
Guava - Runnables.doNothing();
