![]() ![]() you can execute the same jar file in any operating system e.g. ![]() JAR stands for Java Archive and provides a platform-independent deliverable for java programs, libraries and frameworks. JAR file in Java is a kind of zip file that holds all contents of a Java application including Class files, resources such as images, sound files, and optional Manifest files. While ((byteRead = inputStream.read()) != -1) Try to run this program and compare the time with the ones using legacy File I/O (on big files) you will see NIO performs much faster.Creating JAR file in java from the command prompt is always been little tricky for many of us even if IDE like Netbeans and Eclipse provide support to export java program as JAR file simply because we don’t create jar often and not familiar with manifest file or jar command as a whole. OutputStream outputStream = new FileOutputStream(outputFile) InputStream inputStream = new FileInputStream(inputFile) ("Please provide input and output files") * Copy one file to another using low level byte streams, one byte at a time. The source file and destination file are provided from command line’s arguments: import java.io.* Reading and Writing Binary Files Using FileInputStream and FileOutputStreamThe following examples use the FileInputStream and FileOutputStream classes to perform low level binary I/O.This program copies one file to another, one byte at a time. ![]() ![]() Whereas the BufferedInputStream and BufferedOutputStream are more efficient by buffering the input stream and output stream to reduce the number of calls to the native API.Now, let’s see some code examples. Moving down, the implementation classes FileInputStream and FileOutputStream are for reading and writing streams of raw bytes, one or multiple bytes at a time.
