Description

Java I/O ‌It is used to process the input and produce the output. It uses stream to make operations faster. java io package contains all the classes for IO. ‌Stream ‌Sequence of data Stream is made of byte ‌Java FileOutputStream: ‌output stream used for writing data to a file Java FileInputStream : It is used to read data in the form of bytes from file. It is used for reading byte-oriented data like audio, video, image and etc. Java BufferedOutputStream: It internally uses buffer to store data. It is more efficient way to write data than FileOutputStream public class BufferedOutputStream extends FilterOutputStream Java BufferedInputStream: BufferedInputStream class is used to read information from stream It internally uses buffer mechanism to make the performance fast Java SequenceInputStream Java SequenceInputStream class is used to read data from multiple streams. It reads data sequentially Java ByteArrayOutputStream It is used to write common data into multiple files. It holds a copy and forwards it to multiple streams. Java DataOutputStream It writes primitive Java data types to the output stream in a machine-independent way. Java DataInputStream It reads primitive data from the input stream in a machine-independent way. What is character encoding? Since every data in computer is represented in bytes and Strings are essentially collection of characters. To convert bytes into character JVM needs to know which combination of bytes represent which character and this is what character encoding tells JVM. There are many languages in the World like English, Tamil, Telugu and etc. This is the reason why we need to give correct character encoding while converting the bytes to String. Java FileWriter It is used to write character-oriented data to a file. Unlike FileOutputStream class, you don't need to convert string into byte array because it provides method to write string directly. Java BufferedWriter It is used to provide buffering for Writer instance. It makes the performance fast. Who this course is for: High school students who are at early stages of Computer knowledge. College students from CSE, ECE, IT, BSC, MCA, ME, Mtech. IT professionals who are eager to learn new Software technologies.
