Java consumer substitutes?

Question

Where there is already a java substitute for this functional interface:

public interface FunctionA {
       public void run(Person person, Object target);
}

in the form of

BiConsumer<Person, Object>

is there one for this abstract class:

public abstract class ApplicationPlugin {

public abstract void init();

}

where usage is:

public class X extends ApplicationPlugin {
@Override public void init(){
    //stuff
}
}

Answer 1

Yes, you're looking for the Runnable interface which has a single method taking no parameters and has a void return type.

e.g.

Runnable runnable = () -> doSomething();
