Byte Stream vs Character Stream

Byte Stream Class:

• Byte Stream are defined by two hierarchies 

1. InputStream
2. OutputStream

•  The abstract class InputStream and OutputStream define several key method that the other stream classes implement. The two most Important are

1. read()
2. write()

• Stream class (Subclass)
• BufferedInputStream
• BufferedOutputStream
• ByteArrayInputStream
• ByteArrayOutputStream
• DataInputStream
• DataOutputStream
• FileInputStream
• FileOutputStream
• PrintStream
• PushbackInputStream

Character Stream class:

• Character stream are defined by two class hierarchies

1. Reader
2. Writer

• These class handle unicode character stream.
• The most important method are

1. read()
2. write()  which read/write the character of data.

• character classes
• BufferedReader
• BufferedWriter
• CharArrayReader
• CharArrayWriter
• InputStreamReader
• OutputStreamReader
• FileReader
• FileWriter
• PrintWriter
• PushbackReader

 Streams - Byte Based(Read or write Bytes)[Mainly used for Binary files)
Reader - Character Based(Read or Write Character)[for Text files]

 Filereader is the best option as it reads the file characterwise or u can use bufferedreader because it reads stringwise.
