Read and Write text files based on Java I/O Learning

Java I/O operations are performed based on streams. To improve read/write efficiency, buffer is required.

A simple example is as follows:

/**
* Read the content in 1.txt and write it to 2.txt.
*
*/

Import java. io .*;

Public class ReadWriteFile {
Public static void main (String [] args ){
Try {

File read = new File ("c: \ 1.txt ");
File write = new File ("c: \ 2.txt ");

BufferedReader br = new BufferedReader (
New FileReader (read ));
BufferedWriter bw = new BufferedWriter (
New FileWriter (write ));
String temp = null;
Temp = br. readLine ();
While (temp! = Null ){
// Write an object
Bw. write (temp + ""); // applicable only to Windows
// Continue reading the file
Temp = br. readLine ();
}

Bw. close ();
Br. close ();

} Catch (FileNotFoundException e) {// file not found
System. out. println (e );
} Catch (IOException e ){
System. out. println (e );
}
}
}
