Thanks Mansi for sharing your knowledge & Experience ❤️.

Welcome 🙏

[@manishagarwal1505]

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())

[@JavaTechies]

Thank you

[@Anilkumar-reddy]

Thanks Mansi for your extreme efforts, keep it up. we need more videos from you. For the method 8 we can use like these right? Optional min = employeeList.stream().min(Comparator.comparing(Employee :: getYear));

[@priyakoli5572]

Hi Ma'am, First of all Thank you very much for your efforts, its really helpful. wanted to ask one question: in method8 i am getting Optional.empty whereas if i remove either of condition then then o get some result, why so for me?

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()) ));

[@pravinppatil2116]

Examples you have taken here are really helpful, Good Work keep it up. I want you to Correct 1-2 mistakez here while comparing string you have using == operation instead of that we should use equals method.

[@JavaTechies]

Ya, fine, thank you

[@priyakoli5572]

Also for method4, what if we have 2 employees with same highest salary? then it displays only 1 person's salary....why so why not 2 if both have same highest salary?

[@JavaTechies]

Is it using findfirst ??

Hi I have one question where i need to sort based on price. Can you please help Ques: Using Java8, sort the products in "Electronics" and "Accessories" by attribute "price" in desc order? public static void sortData() { List electronics = new ArrayList(); Map map1 = new HashMap(); map1.put("price", "100"); map1.put("name", "Camera"); Map map2 = new HashMap(); map2.put("price", "200"); map2.put("name", "Laptop"); Map map3 = new HashMap(); map3.put("price", "90"); map3.put("name", "WebCam"); electronics.add(map1); electronics.add(map2); electronics.add(map3); // Comparator.comparing() ->Integer.parseInt(); List accessories = new ArrayList(); Map amap1 = new HashMap(); amap1.put("price", "50"); amap1.put("name", "CameraBag"); Map amap2 = new HashMap(); amap2.put("price", "80"); amap2.put("name", "LaptopBag"); Map amap3 = new HashMap(); amap3.put("price", "10"); amap3.put("name", "MousePad"); accessories.add(amap1); accessories.add(amap2); accessories.add(amap3); Map input = new HashMap(); input.put("Electronics", electronics); input.put("Accessories", accessories); }

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()));
