FileInputStream fis = new FileInputStream("example.txt"); FileChannel channel = fis.getChannel();
FileInputStream fis = new FileInputStream("example.txt"); FileChannel channel = fis.getChannel(); ByteBuffer buffer = ByteBuffer.allocate(1024); int bytesRead = channel.read(buffer);In this example, we create a ByteBuffer with size 1024, and then read data from the FileChannel into the ByteBuffer using the read() method. Overall, the java.io.FileInputStream.getChannel() method is used to get the channel associated with the file input stream, which can then be used to perform various operations on the file, such as reading or writing data.
