What is the difference between Java – takeWhile and filters?

How is takeWhile () different from filter () in Java 9 What additional utilities does it have?

Stream.of(1,2,3,4,5,6,7,8,9,10).filter(i -> i < 4 )
        .forEach(System.out::println);

This may be what the following will do

Stream.of(1,10).takeWhile(i -> i < 4 )
        .forEach(System.out::println);

So what does this new feature need?

Solution

Filter will delete all items that do not meet the conditions from the stream

TakeWhile will abort the flow the first time an item does not meet the criteria

for example

Stream.of(1,10,1)
    .filter(i -> i < 4 )
    .forEach(System.out::print);

Will print

but

Stream.of(1,1)
    .takeWhile(i -> i < 4 )
    .forEach(System.out::print);

Will print
