How to take Two files as input

[Vivekkk Singh]

Hi i want to take two files as input from command prompt

 public class ReadNWrite {

	/**
	 * @param args
	 * @throws FileNotFoundException 
	 */
	public static void main(String[] args) throws FileNotFoundException {
		// TODO Auto-generated method stub
		String inputFile=args[0];
		String outputFile=args[1];
		FileInputStream inputStream = new FileInputStream(inputFile);
		FileOutputStream outputStream=new FileOutputStream(outputFile);
		DataInputStream in = new DataInputStream(inputStream);
		DataOutputStream out=new DataOutputStream(outputStream);
	    BufferedReader inputRead = new BufferedReader(new InputStreamReader(in));
	    String lines;
	   try {
		while((lines=inputRead.readLine())!=null)
		   {
			   System.out.println(lines);
		   }
	} catch (IOException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
	
}

}   

So when i am running it :- java ReadNWrite Input.txt Output.txt
I get an Error

Exception in thread "main" java.lang.NoClassDefFoundError: ReadNWrite/java
Caused by: java.lang.ClassNotFoundException: ReadNWrite.java

Please help!!!

It is looking for a class named "java" in the ReadNWrite package. This is generally caused by accidentally using the ".java" extension when running. Perhaps you did this...

java ReadNWrite.java Input.txt Output.txt

Instead of...

java ReadNWrite Input.txt Output.txt

Do you have a package for this class?

javac ReadWirter.java

java ReadWriter input.txt output.txt
