Question

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

Answer 1

The C0DE

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.

See attachment for result.
