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...
In the given example, we are converting a stream to an array using usingtoArray()API. It uses theString[]::newgenerator function for creating a new array of typeString. This is equivalent to writing alambda expressionthat creates a newStringarray, such as ‘size -> new String[size]‘. ...
