InputStream -> To read data from a source. OutputStream -> To write data to a destination. ByteStreams -> Classes related to 8-bit Bytes. Most important among them include 1)File InputStream-For reading data from files. 2)File OutputStream-To create a file and/or write data into it. // Headers used include import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.io.FileInputStream; import java.io.FileOutputStream; //etc. //Sample program with Buffered Reader public class NewClass { public static void main(String[] args) throws IOException{ BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); System.out.println("Enter content"); String s = br.readLine(); System.out.println("Entered content is "+s); } }
