They have created streams so that we don't have to use our brains to think on the logic and simply learn the infinite number of functions and try to find a way to use them. Streams api is completely useless, I can't think complex logic in streams. Streams are not made for humans , they are made for machines.

Hi thanks for this informative vdo, but can you please make vdo for if two different application running in different port. How to run and stop the server???
Nice catch, I just made the small fix changed to: if (c1 == c2){ Meta.temp++; } else { Meta.temp = 1; // reset counter } if (Meta.temp > Meta.total){ Meta.total = Meta.temp; Meta.aChar = c1; } return c2;
I tried this code and it only fetches a single employee getting highest salary from each department. Even though there are multiple employees getting same highest salary. Can you write a code to fetch all the employees from each department getting highest salary. for example 2 employees from HR department gets the same highest salary 10000. So in output I want both the employee details.
IMO, the best metaphor which fits the problem is to make a cake and to go to the grocery N times for buying each ingredient one by one. Would we really do that so? LOL Better to learn a pattern to write entities and queries to prevent performance issue right now ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mJrrJEIQxOQ.html
Can you write a program to get top 5 salaries and Employees name given they have Employee ID , Employee NAme , Employee Department , Employee Salary , Employee isActive boolean true property. Please explain in easy words and execute and write program using java 8 functional programming features and streams to Pick only the TOP 5 salary and top 5 Employee Name only. I tried with this following approach but interviewer rejected me and i am not able to solve. Please explain how to write the solution because i am crying so much. public class Employee { //id,name,department,salary,isActive; //Find out top 5 IT department, <50 K, isActive='true' public static void main(String[] args) { // TODO Auto-generated method stub // topEmployeeList = allEmployeeList.stream() .filter(department=='IT') .filter(salary<50000) .filter(isActive==true) .collect(groupingBy(e->e.department, collectingAndThen(maxBy(comparingInt(e->e.salary))))); } }
Streams are waste of time. For interviews, I have to byheart the code for different programs and I can't simply think in terms of streams. I want to personally punch the java creators for creating streams.
