We can copy a file from one location to another using FileInputStream and FileOutputStream classes in Java.
For this we have to import some specific classes of java.io package. So for instance let us include the entire package with statement import java.io.*;
The main logic of copying file is to read the file associated to FileInputStream variable and write the read contents into the file associated with FileOutputStream variable.
Methods used in the program
- int read(); Reads a byte of data. Present in FileInputStream. Other versions of this method : int read(byte bytearray) and int read(byte bytearray, int offset, int length)
- void write(int b) : Writes a byte of data. Present in FileOutputStream. Other versions of this method : void write(byte bytearray) and void write(byte bytearray, int offset, int length);
