zip() and zipWith()

Comment

zip() zips two publishers together

Zip is static method

Can be used to merge 2-8 publishers

zipWith():-

This is instance method

User to merge 2 publs inot 1

Waits for publishers involved in transformation to emit one elimt

Continues until one publisher sends onComplete() event

 public Flux<String> explore_zip() {

        var abcFlux = Flux.just("A", "B", "C");

        var defFlux = Flux.just("D", "E", "F");

        return Flux.zip(abcFlux, defFlux, (first, second) -> first + second).log();


    }

    // AD14, BE25, CF36
    public Flux<String> explore_zip_1() {

        var abcFlux = Flux.just("A", "B", "C");
        var defFlux = Flux.just("D", "E", "F");
        var flux3 = Flux.just("1", "2", "3");
        var flux4 = Flux.just("4", "5", "6");

        return Flux.zip(abcFlux, defFlux, flux3, flux4)
                .map(t4 -> t4.getT1() + t4.getT2() + t4.getT3() + t4.getT4()).log();


    }

    public Flux<String> explore_zip_2() {

        var aMono = Mono.just("A");
        var bMono = Mono.just("B");


        return Flux.zip(aMono, bMono, (first, second) -> first + second).log();


    }

    // AD, BE, CF
    public Flux<String> explore_zipWith() {

        var abcFlux = Flux.just("A", "B", "C");

        var defFlux = Flux.just("D", "E", "F");

        return abcFlux.zipWith(defFlux, (first, second) -> first + second).log();


    }

    public Mono<String> explore_zipWith_mono() {

        var aMono = Mono.just("A");

        var bMono = Mono.just("B");

        return aMono.zipWith(bMono)
                .map(t2 -> t2.getT1() + t2.getT2()).log();

    }
