rx-java Getting started with rx-java Hello, World!
Example
The following prints the message Hello, World! to console
public void hello() {
Observable.just("Hello, World!") // create new observable
.subscribe(new Action1<String>() { // subscribe and perform action
@Override
public void call(String st) {
System.out.println(st);
}
});
}
Or using Java 8 lambda notation
public void hello() {
Observable.just("Hello, World!") // create new observable
.subscribe(onNext -> { // subscribe and perform action
System.out.println(onNext);
});
}
