What are the uses of File Input Stream and File Output Stream in java programming?
These streams are classified as mode streams as they read and write data from disk files. the classes associated with these streams have constructos that allows us to specify the path of the file to which they are connected. The FileInputStream class allows us to read input from a file in the form of a stream. The FileOutputStream class allows us to write output to a file stream. Example, FileInputStream inputfile = new FileInputStream ("Empolyee.dat"); FileOutputStream outputfile = new FileOutputStream ("binus.dat");

To read data which is superior 1. input stream 2. file reader?
First of all, these two classes are on different levels of abstraction. An InputStream is used for reading any stream of bytes, while a FileReader is used to read characters from a file. If you want to ask between a FileInputStream and a FileReader, then we need to look at what type of data you are reading. If you're reading plain-text file, for example, you want to use a FileReader because it was designed to read in characters. For other types of data, the FileInputStream would be better, as it is used to read in generic streams of bytes from a file.
Java program that reads a file and display the file on the screen with a line number before each line?
