There are so many features in java.io
Which includes the BufferedReader Writer etc.
BufferedReader
Hierarchy for Output Classes
- Writer, streams buffers and output streams.
Reading from the Java Console.
- Scanner class encapsulates all this reading and writing.
Alternative coding
BufferedReader br = new BufferedReader
- can readline and close Java closes when the program terminates but you should always close the file.
System.in Object
- Wrapping in a hierarchy just to read input from the user.
- Whatever the users types the return type will always be a string because of the wrapping.
java.io package
- Reader, streams and buffers and readers.
- You can read and write objects but only if they were read and written as objects in the first place.
