InputStream inputStream = new ByteArrayInputStream(bytes); In the provided code block, we create abytearray namedbytesto hold theUTF-8encoded representation of the provided text lines. Then, we use theByteArrayInputStream(bytes)to create anInputStreamnamedinputStreamfrom thisbytearray. This setup...
// Java 8, Convert all Map values to a List List<String> result4 = map.values().stream() .collect(Collectors.toList()); // Java 8, seem a bit long, but you can enjoy the Stream features like filter and etc. List<String> result5 = map.values().stream() ...
