July 28, 2025 - If you prefer a more compact way to write that filtering step, Java’s stream API lets you handle it in a single line while keeping things readable. Streams turn arrays or collections into pipelines, where each item flows through a series of operations. Here’s a version that matches the manual loop above: List<String> filteredWords = Arrays.stream(words) .map(String::trim) .filter(s -> !s.isEmpty()) .collect(Collectors.toList());

Arrays.asList() would do the trick here.
String[] words = {"ace", "boom", "crew", "dog", "eon"};
List<String> wordList = Arrays.asList(words);
For converting to Set, you can do as below
Set<T> mySet = new HashSet<T>(Arrays.asList(words));

The easiest way would be:
String[] myArray = ...;
List<String> strs = Arrays.asList(myArray);
using the handy Arrays utility class. Note, that you can even do
List<String> strs = Arrays.asList("a", "b", "c");

In Java 8 or later:
String listString = String.join(", ", list);
In case the list is not of type String, a joining collector can be used:
String listString = list.stream().map(Object::toString)
.collect(Collectors.joining(", "));

If you happen to be doing this on Android, there is a nice utility for this called TextUtils which has a .join(String delimiter, Iterable) method.
List<String> list = new ArrayList<String>();
list.add("Item 1");
list.add("Item 2");
String joined = TextUtils.join(", ", list);
Obviously not much use outside of Android, but figured I'd add it to this thread...

List<String> strings = Arrays.asList(new String[]{"one", "two", "three"});
This is a list view of the array, the list is partly unmodifiable, you can't add or delete elements. But the time complexity is O(1).
If you want a modifiable a List:
List<String> strings =
new ArrayList<String>(Arrays.asList(new String[]{"one", "two", "three"}));
This will copy all elements from the source array into a new list (complexity: O(n))

Use the static List list = Arrays.asList(stringArray) or you could just iterate over the array and add the strings to the list.
