15 seconds Average the speed and accelration and replace the values in upcoming streams












0














 KTable<Windowed<String>,Demo1> windowstream = dummy1
.groupByKey(Serialized.with(Serializer.getSerde(String.class), Serializer.getSerde(Demo1.class)))
.windowedBy(TimeWindows.of(TimeUnit.SECONDS.toMillis(15))).aggregate(new Initializer<Demo1>() {
@Override
public Demo1 apply() {

return new Demo1();
}
}, new Aggregator<String, Demo1, Demo1>() {
@Override
public Demo1 apply(String key, Demo1 value, Demo1 aggregate) {

double u= value.getspeed();
double v= value.getaccelraton();
System.out.println("Speed====" + value.getspeed() + "Accelration===" + value.getaccelraton());
return aggregate;
}
});


This code is running but i want to take average of speed and accelration and replace values of both entity in upcoming stream data.
