Java 8 Stream - filter and map Example

We've talked about using java.util.stream.forEach and java.util.stream.anyMatch in prior posts.  Today we're going to talk about the filter and map features of the java.util.stream package.

The filter feature takes a Predicate and returns a java.util.stream consisting of data elements that matched that Predicate condition.

The map feature takes a custom function and returns a new java.util.stream consisting of the response from that function.

You can then use java.util.stream.collect and java.util.stream.collectors.toList() to reduce the stream to a java.util.List

For your reference, we have created a filter and map example you can take a look at here  -- https://github.com/daveschickconsulting/java_8_examples/blob/main/src/funwithjava8streams/MainExample_filterAndMap.java
