InputStream to String Java In Java, converting an InputStream to a String is a common task, often needed for reading data from files, network connections, or APIs. This can be achieved using classes like BufferedReader, InputStreamReader, or utilities like new String(inputStream.readAllBytes()) in Java 9 and later. Alternatively, the Scanner class with useDelimiter("\\A") can read the entire stream as a single String. These methods are efficient for processing text data and are frequently used in applications like file parsing and web service integration
