    Hi Boaz
    Core Java:http://www.javatpoint.com/
    As for Java Input/Output study reading and writing of files using the various classes(BufferedReader,InputStreamReader) and the difference between them.
    There is whole lot of other stuff to study.Don't stop here.These are just the basics.
    Good Luck

    Java I/O is used to process the input and produce the output. Java uses the concept of stream to make I/O operation fast. The java.io package contains all the classes required for input and output operations.

    Java uses the concept of a stream to make I/O operation fast. The java.io package contains all the classes required for input and output operations.

    We can perform file handling in Java by Java I/O API.

    Stream
    A stream is a sequence of data. In Java, a stream is composed of bytes. It's called a stream because it is like a stream of water that continues to flow.

    In Java, 3 streams are created for us automatically. All these streams are attached with the console.

    1) System.out: standard output stream

    2) System.in: standard input stream

    3) System.err: standard error stream

    Let's see the code to print output and an error message to the console.

    Let's see the code to get input from console.

    The import is use to include something in our java program.the IO is The Basic Input Output From the user to java applicationso,If You Want to use input from the user side at the black console than you have to use import java.io.* package or super class that has all the method and function to performing operations like “Input From user”
    Bcoz the Java Input Is Uses Bufferized Input.
