KStream<String, dummy> demoZone = builder.stream(fromTopic, Consumed.with(Serializer.getSerde(String.class), Serializer.getSerde(dummy.class)));
I want to apply window on demoZone of 1 minutes and find average of that 1 min data

You can use TimeWindow as given below :
KTable<Windowed<String>, Long> averageCount = demoZone
.groupByKey(Serialized.with(Serdes.String(), dummySerde()))
.windowedBy(TimeWindows.of(TimeUnit.MINUTES.toMillis(5).advanceBy(TimeUnit.MINUTES.toMillis(1))))
.reduce(// Your aggregate logic here);
You can find more details about Windowing here :

thanks it's working .....
