@WhiteObama112 Год назад

for the question no 12 - I did some changes, here we need the list of names for each department which can be done with only stream like below. Map namesByDept = employeeList.stream().collect( Collectors.groupingBy(Employee::getDepartment) ) .entrySet().stream() .collect(Collectors.toMap(o -> o.getKey(), o -> o.getValue() .stream() .map(m -> m.getName()) .collect(Collectors.toList()) ));

Hi I have one question where i need to sort based on price.

Good tutorial for java streams and lambda. Though I noticed that you used == for string comparison while we should use .equals something like "Male".equals(x.getGender())

@girish44444 Год назад

If there is more than 1 highest paid employee then it will give wrong result I think? For that : empList.stream() .collect(Collectors.groupingBy(Employee::getSalary, TreeMap::new, Collectors.toList())) .lastEntry() // for lowest salary you should use firstEntry; .getValue().forEach(entry -> System.out.println("Name : "+entry.getName() + " , "+ "Salary : "+ entry.getSalary()));
