How to filter String list by starting value in Java?
Let’s first create a String list −
List list = new ArrayList<>();
list.add("wxy");
list.add("zabc");
list.add("ddd2");
list.add("def");
list.add("ghi");
list.add("wer");
list.add("uij");
list.add("wqy");To filter String list by starting value, use filter() and startsWith() −
list.stream().filter((b) -> b.startsWith("w"))The following is an example to filter string list by starting value −
Example
import java.util.ArrayList;
import java.util.List;
public class Demo {
public static void main(final String[] args) {
List list = new ArrayList<>();
list.add("wxy");
list.add("zabc");
list.add("ddd2");
list.add("def");
list.add("ghi");
list.add("wer");
list.add("uij");
list.add("wqy");
System.out.println("List beginning with letter w = ");
list.stream().filter((b) -> b.startsWith("w"))
.forEach(System.out::println);
}
}Output
List beginning with letter w = wxy wer wqy
