To use it, we need to add import java.io.IOException; to the top of any file that uses the exception (java.io is a package, as we'll see in a future tutorial). Below programs illustrate the above function: Program 1: import java.util. Another solution is to use the BufferedReader.The following code read streams of raw bytes using InputStream and decodes them into characters using a specified charset using an InputStreamReader, and form a string using a platform-dependent line separator.Here, each invocation of the readLine() method would read bytes from the file and . To get everything working, I use the Benhui example. import java.util.Scanner; import static java.lang.System.out; The programmer needs to subclass the IOException and should throw the IOException subclass based on the context. Examples Example resource directory structure When an exception occurs in the program, the program execution is terminated. Using Java 7 ( java.nio.file.Files.readAllBytes) To read all the bytes from a file, we can use the readAllBytes () method, which takes the path to the file and returns a byte array containing the bytes read from the file.
