Filter collection in Java 8

Filter collection in Java 8

Hi,

I have following collection:

List<String> listBoks = new ArrayList<>(
Arrays.asList("Learn Java in a Day",
          "Learn Java Easily",
          "Learn PHP",
           "Learn iOS programming"));

I want to filter out this array and only get data containing Java in it.

How to filter this using the Java 8?

Thanks

Hi,

Example of Filter collection in Java 8

You can use the following code in Java 8:

listBoks.removeIf(s -> !s.contains("Java"));

Above code will remove all the data not containing "Java".

Thanks
