	➝5	The main method begins by calling a method named getMovies,
	which returns an array of Movie objects to be written to the file. (The Movie class is defined as an inner class later in the program.) Then it calls openWriter, which creates a PrintWriter object that the program can use to write data to the file. Next, it uses an enhanced for loop to call the writeMovie method for each movie in the array. This method accepts a Movie object that contains the movie to be written and a PrintWriter object to write the movie to. Finally, the PrintWriter is closed.

Reading Binary Streams

✦ BufferedInputStream: This class adds buffering to the basic
FileInputStream, which improves the stream’s efficiency and gives it a moist and chewy texture.

Reading Binary Streams	755


Constructors	Description

BufferedInputStream (InputStream in)

Creates a file input stream from
the specified object. It throws
FileNotFoundException if the file doesn’t exist or if it’s a directory rather than a file.

FileInputStream(String path)


	Reads a boolean value	Book VIII
	from the input stream. It	Chapter 2


	Reads a byte value from the input
	stream. It throws EOFException

char readChar()	Reads a char value from the input
	stream. It throws EOFException
	and IOException.

Constructors	Description

double readDouble()

Reads an int value from the input stream. It throws EOFException and IOException.

long readLong()

Reads a string stored in UTF format from the input stream. It throws
EOFException, IOException, and UTFDataFormatException.

The following sections present programs that read and write data in a binary file named movies.dat that contains information about movies. Each record in this file consists of a UTF string containing the movie’s title, an int repre-senting the year when the movie was released, and a double representing the price I paid for the movie at my local discount video store. Although the format of this file is different from that of the movies.txt file shown earlier in this chapter, the file contains the same data. Refer to the section “Reading Character Streams,” earlier in this chapter, to see a list of the movies in this file.
