Java 8 Stream - How to Sort a List using lambda | Example | Java Techie 

Thanks buddy glad that i am delivering the content which people can understand. Keep learning

Keep learning 😃

It's always recommend to use stream in single pipeline rather than use collections utility method

@@Javatechie Thanks for the information 🙂 I just felt that if all I want to do is sort the stream and not worry about modifying the original list, and not perform any other operation like 'filtering' or 'mapping' then creating a stream will incur extra overhead.

Thank you so much subham

After finish this stream API we will start date API series

@@Javatechie Thank you...

Thanks buddy 😊

We can't represent this as Method reference

@Java Techie ... Thank you

Link mentioned in video description

Method reference doesn't mean to access only static method all getter method you can access while performing mapping

Thank you 😀

You can call reverseOrder ()

@@Javatechie Thanks

Yes we can , you need to do something like list.stream().sort(Comparator.comparing("ADD COMPARISON LOGIC")).collect(Collectors.toList());

import java.util.List; import java.util.ArrayList; import java.util.stream.Collectors; import java.util.Comparator; public class Main { public static void main(String[] args) { List numbers = List.of(3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5); List sortedNumbers = new ArrayList(); while (!numbers.isEmpty()) { Integer min = numbers.stream() .min(Comparator.naturalOrder()) .orElse(null); if (min != null) { sortedNumbers.add(min); numbers.remove(min); } } System.out.println(sortedNumbers); } }

Just use reversed () method

@@Javatechie Thanks alot and response also so fast

Is it works?

@@Javatechie yes

If you won't override equals and hashcode then we can't compare object This is what also contract between these two method

Do you have setter and getter method define in your employee class

@@Javatechie i think its just STS not showing the methods … when i wrote manually there is no error

Ok Will do

@@Javatechie thanks ☺️☺️

Inside lambda we need to go for if condition

Why doing stream you should forcefully either make them lowercase or uppercase something like employees.stream().sorted(Comparator.comparing(emp->emp.getName().toLowerCase())).forEach(System.out::println);

@@Javatechie Collections.sort(employee,(o1,o2)-> o1.getName().compareToIgnoreCase(o2.getName())); like that working but in stream is not working
