Java 8. Is it a good or bad practice to pass a method which changes a state of a class as Runnable into another method of this class - java-8

Question

Just noticed an interesting feature of Java 8. This actually helped me to avoid lots of refactoring but I'm not sure if this is good to do like that.
So dear Stackoverflowers, could you tell me whether this correct or not?
Here is simply what I've done
E.g. there is a service which I want to execute and it should have execution modes
import java.time.LocalDate;
#Service
public class SomeService {
#Value("${com.example.url.mode.1}")
private String runnerURLmode1;
#Value("${com.example.url.mode.2}")
private String runnerURLmode2;
#Value("${example.url.mode.3}")
private String runnerURLmode3;
private String modeDependingField1;
private Integer modeDependingField2;
private LocalDate modeDependingField3;
public void setMode1() {
modeDependingField1 = runnerURLmode1;
modeDependingField2 = 1;
modeDependingField3 = LocalDate.now();
}
public void setMode2() {
modeDependingField1 = runnerURLmode2;
modeDependingField2 = 2;
modeDependingField3 = LocalDate.now().minusDays(2);
}
public void setMode3() {
modeDependingField1 = runnerURLmode3;
modeDependingField2 = 3;
modeDependingField3 = LocalDate.now().minusDays(5);
}
public void execute(Runnable mode) {
mode.run();
System.out.println(toString());
}
#Override
public String toString() {
return "modeDependingField1: " + modeDependingField1 + "\n" +
"modeDependingField2: " + modeDependingField2 + "\n" +
"modeDependingField3: " + modeDependingField3;
}
}
And a service consumer
public class ServiceExecutor {
public static void main(String[] args) {
SomeService someService = new SomeService();
System.out.println("========= Executin mode 1 ===========");
someService.execute(someService::setMode1);
System.out.println("\n\n========= Executin mode 2 ===========");
someService.execute(someService::setMode2);
System.out.println("\n\n========= Executin mode 3 ===========");
someService.execute(someService::setMode3);
}
}
So I get the output:
========= Executin mode 1 ===========
modeDependingField1: 1
modeDependingField2: 1
modeDependingField3: 2017-05-03
========= Executin mode 2 ===========
modeDependingField1: 2
modeDependingField2: 2
modeDependingField3: 2017-05-01
========= Executin mode 3 ===========
modeDependingField1: 3
modeDependingField2: 3
modeDependingField3: 2017-04-28
