Question

i have to write a program that asks the names of 2 files. the first should be open for reading second for writing. the program should read the the contents of the first file change all characters to uppercase and store in the second file. the second file will be a copy of the first file, except that all characters will be uppercase. use notepad to test the program. i got this so far {
        String firstfile;
        String secondfile;
       
    Scanner keyboard;
            keyboard = new Scanner (System.in);
           
    System.out.println("Enter the first file name");
    firstfile = keyboard.nextLine();
   
    File readfile = new File(firstfile);
    Scanner inputFile = new Scanner(readfile);
   
    System.out.println("Enter second file name");
    secondfile = keyboard.nextLine();
    PrintWriter outputFile = new PrintWriter(secondfile);
      while (inputFile.hasNext())
      {
          String line = inputFile.nextLine();
          outputFile.println(line.toUpperCase());
         
      }
      inputFile.close();
      outputFile.close();

import java.util.*;
import java.io.*;
public class Test{
   public static void main(String args[]) throws Exception
   {
       String firstfile;
       String secondfile;
      
       Scanner keyboard;
       keyboard = new Scanner (System.in);
      
       System.out.println("Enter the first file name");
       firstfile = keyboard.nextLine();
      
       File readfile = new File(firstfile);
       Scanner inputFile = new Scanner(readfile);
      
       System.out.println("Enter second file name");
       secondfile = keyboard.nextLine();
       PrintWriter outputFile = new PrintWriter(secondfile);
       while (inputFile.hasNext())
       {
           String line = inputFile.nextLine();
           outputFile.println(line.toUpperCase());
          
       }
       inputFile.close();
       outputFile.close();
   }
}

/* run the program as followed

C:\Users\A nariaRa\Desktop〉javac Test.java C:AUsersAmarlaRa \Desktop>java Test Enter the first file name a.txt Enter second file name b.txt

Now open b.txt in notepad to check the contents of the file.
