Input & Output Stream

Output Stream

     The java application used to the output stream write the data to destination.

5 types below;

1. FileOutputStream,
2. ByteArrayOutputStream,
3. FilterOutputStream,
4. PipedOutputStream,
5. ObjectOutputStream,

Filter OutputStream 

3 types below:

1. DataOutputStream
2. BufferedOutputStream
3. printStream

Input Stream

   The java application used to the input stream in read data from source...

6 types below:

1. FileInputStream
2. ByteArrayInputStream,
3. FilterInpuStream,
4. SequenceInputStream
5. PipedInputStream
6. ObjectInputStream,

FilterInputStream

3 types :

1. DataInputStream,
2. BufferedInputStream,
3. PushbackInputStream

File Input Stream

Program:

public class Demo {

public static void main(String[] args) {

try{  

   FileInputStream fin=new FileInputStream("D:\\MANIKATTI.K.doc");  

   int i=0;  

   while((i=fin.read())!=-1){  

    System.out.println((char)i);  

   }  

   fin.close();  

 }catch(Exception e){System.out.println(e);}  

}

}

File Output Stream

Program :



public class Demo {

public static void main(String[] args) {
try{
FileOutputStream fin=new FileOutputStream("D:\\MANIKATTI.K.doc");
String a="Welcome to Friends";
byte[] b=a.getBytes();
fin.write(b);
fin.close();
System.out.println("Success");
}catch(Exception e){System.out.println(e);}
}

}

Byte Array Output Stream

public class Demo1 {

public static void main(String[] args) throws IOException {

try {

FileOutputStream f=new FileOutputStream("D:\\MANI.doc");

FileOutputStream f1=new FileOutputStream("D:\\MANIKATTI.K.doc");

String a="welcome";

byte[] s=a.getBytes();

f.write(s);

ByteArrayOutputStream by=new ByteArrayOutputStream();

by.write(s);

by.writeTo(f);

by.writeTo(f1);

by.flush();

by.close();

System.out.println("true");

} catch (FileNotFoundException e) {

e.printStackTrace();

}

}

}

Sequence InputStream :

public class Demo1 {

public static void main(String[] args) throws Exception {

try {

FileInputStream f=new FileInputStream("D:\\MANI.doc");

FileInputStream f1=new FileInputStream("D:\\MANIKATTI.K.doc");

SequenceInputStream s=new SequenceInputStream(f, f1);

int i;

while((i=s.read())!=-1){

System.out.println((char)i);

}

} catch (FileNotFoundException e) {

e.printStackTrace();

}

}

}

public class Demo2 {

public static void main(String[] args) throws Exception {

try {
FileInputStream f=new FileInputStream("D:\\MANI.doc");
FileInputStream f1=new FileInputStream("D:\\MANIKATTI.K.doc");
FileOutputStream fout=new FileOutputStream("D:\\MANIK.doc");

SequenceInputStream sis=new SequenceInputStream(f,f1);
int i;
while((i=sis.read())!=-1){
fout.write(i);
}
f.close();
f1.close();
fout.close();
sis.close();

} catch (FileNotFoundException e) {
e.printStackTrace();
}

}

}
