Write a java program to copy the content of one file in to another file

Answer»

import java.io.FILEINPUTSTREAM;

import java.io.FileOutputStream;

class File_demo {

public static void main(String[] args) {

byte[] array = new byte[50];

try {

FileInputStream sourceFile = new FileInputStream("input.txt");

FileOutputStream destFile = new FileOutputStream("output.txt");

// reads all DATA from input.txt

sourceFile.read(array);

// writes all data to newFile

destFile.write(array);

System.out.println("The input.txt file is COPIED to newFile.");

// CLOSES the stream

sourceFile.close();

destFile.close();

}

CATCH (Exception e) {

e.getStackTrace();

}

If you run the program the contents of input.txt will be copied to output.txt file.
