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
