Bro.. I got a question, is it possible to get 25LPA hike? Which company wil gv tht much?
I have 5.10 years experience as a java backend developer but current CTC is 7LPA..

[@DrunkenEngineer]

It is very much possible, if you have hands on experience on the latest technologies.

[@Akash-si3el]

@@DrunkenEngineer so java and spring boot is not latest technology for greater hike?

[@DrunkenEngineer]

90% of Java developers know Java and Springboot.
Why will it make you pay higher package?

[@eswarr7189]

empList.stream().collect(Collectors.partitionBy(e -> e.getActive() == 'isActive))): it returns map with active employelist and inactive employelist
