5. Write a simple java program that reads data from one file and writes data to another file.

import java.io.*;
import java.util.Scanner;

public class ExamQ {
    public static void main(String[] args) throws IOException {
        FileInputStream vowel = new FileInputStream("Vowel.txt");
        FileOutputStream constant = new FileOutputStream("Cons.txt");

        int temp = vowel.read();
              while(temp!=-1){
                  constant.write(temp);
                  temp = vowel.read();
              }



      vowel.close();
      constant.close();
    }
}
