== Copy byte between BufferedInputStream and BufferedOutputStream ==



<source lang="java">

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
class BufferedCopy {
public static void main(String[] args) throws Exception {
BufferedInputStream bis = null;
BufferedOutputStream bos = null;
FileInputStream fis = new FileInputStream(args[0]);
bis = new BufferedInputStream(fis);
FileOutputStream fos = new FileOutputStream(args[1]);
bos = new BufferedOutputStream(fos);
int byte_;
while ((byte_ = bis.read()) != -1)
bos.write(byte_);
}
}

</source>



== Create BufferedInputStream from FileInputStream ==



<source lang="java">

import java.io.BufferedInputStream;
import java.io.FileInputStream;
class BufferedInputStreamDemo {
public static void main(String args[]) throws Exception {
FileInputStream fis = new FileInputStream(args[0]);
BufferedInputStream bis = new BufferedInputStream(fis);
int i;
while ((i = bis.read()) != -1) {
System.out.println(i);
}
fis.close();
}
}

</source>



== Import a file of exported preference data. ==



<source lang="java">

import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;
import java.util.prefs.Preferences;
public class Main {
public static void main(String[] argv) throws Exception {
// Create an input stream on a file
InputStream is = new BufferedInputStream(new FileInputStream("output.xml"));
// Import preference data

== Read File in String Using Java BufferedInputStream Example ==



<source lang="java">

import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
public class Main {
public static void main(String[] args) throws Exception {
File file = new File("C:/ReadFile.txt");
FileInputStream fin = new FileInputStream(file);
BufferedInputStream bin = new BufferedInputStream(fin);
byte[] contents = new byte[1024];
int bytesRead = 0;
String strFileContents;
while ((bytesRead = bin.read(contents)) != -1) {
strFileContents = new String(contents, 0, bytesRead);
System.out.print(strFileContents);
}
bin.close();
}
}

== Read from file with BufferedInputStream ==



<source lang="java">

import java.io.BufferedInputStream;
import java.io.FileInputStream;
public class Main {
public static void main(String[] args) throws Exception {
byte[] buffer = new byte[1024];
BufferedInputStream bufferedInput = new BufferedInputStream(new FileInputStream("filename.txt"));
int bytesRead = 0;
while ((bytesRead = bufferedInput.read(buffer)) != -1) {
String chunk = new String(buffer, 0, bytesRead);
System.out.print(chunk);
}
bufferedInput.close();
}
}

</source>



== Use buffered streams to copy a file ==



<source lang="java">

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
public class Main {
public static void main(String[] argv) throws Exception {
BufferedInputStream fin = new BufferedInputStream(new FileInputStream("in.dat"));
BufferedOutputStream fout = new BufferedOutputStream(new FileOutputStream("out.dat"));
int i;
do {
i = fin.read();
if (i != -1)
fout.write(i);
} while (i != -1);
fin.close();
fout.close();
}
}
