Hey Naveen thanks for the video This would also do without using map and method reference. But your video give more Java 8 features, that's also excellent.
List<Integer> integersStartingWith = integerList.stream().filter(e ->
e.toString().charAt(0) == '2'

[gauravshirskar]

e -> e.startsWith("2") || e.startsWith("-2")

[venkatpullamsetty]

Predicate<Integer> startsWith2 = e -> e.startsWith("2");
Predicate<Integer> startsWithNegative2 = e -> e.startsWith("-2");

numbers.stream()
.map(e -> String.valueOf(e))

.map(Integer::value of)

This question was asked in an interview I had.

[shaikjareena]

Stream<String> map = i.stream().map(v->String .valueOf(v));

[prakashkhulbe]

List<Integer> myList=list3.stream().

map(e->Integer.valueOf(e)).
collect(Collectors.toList());

Hi Naveen, I am learning this lambda concept. Can you show the same program without lambda concepts.

Given Array {"abc", "bca", "cab", "cba", "def", …​} expected o/p = "bca", "abc", "cba" ... can anyone help with this using Streams

[yogidilip]

list.stream().filter( e -> String.valueOf( e ).startsWith( "2" ) ).toList();

[ashishsingh]

public class NumberStartWith {
public static void main(String[] args) {
List<Integer> list = Arrays.asList(12, -22, 26, 35, 26, 78, 20, 14, 13, 23);
List<Integer> collect = list.stream().map(e -> String.valueOf(e))
.filter(e -> e.startsWith("2") ||



}
}

[anirudhc]

List<Integer> l = list.stream().filter(n ->

[gktechies.k]

tried this way :) --> list.stream().filter(integer -> integer.toString().charAt(0) == '2' ||

[sunilkumar-svc]

List<Integer> numList4 = new ArrayList<Integer>(
Arrays.asList(213, 215, -250, 250, 32, 24, 43, 57, -39, -212, 113, 34, 45, -2, 144));
-> n.startsWith("2") || n.startsWith("-2"))
-> System.out.println("Number Starts with 2 -->" + n));

[surya]

Stream<Integer> of = Stream.of(2, 203, 240, 2230, 15);
List<Integer> list = -> a.startsWith("2"))
.map(Integer::valueOf)
.toList();


list.forEach(a -> System.out.print(a + " "));

[anushreesonawane]

e->e.startsWith("-2") || e.startsWith("2")
