Question
Create a Java NetBeans project named AddLineNumbers with the main class named AddLineNumbers . This program will read data from a text file "dataInput.txt" and while there are more records, prepend a line number to the text data and output the concatenated data to "dataOutput.txt" implementing a try/catch block to catch any file errors thrown by the JVM. After you have created your NetBeans project AddLineNumbers and before you attempt to execute your application download and/or copy the text data file dataInput.txt from below to your AddLineNumbers project folder. * PLEASE FOLLOW THE INSTRUCTIONS AND STRUCTURE AS STRICTLY AS POSSIBLE. *
After you have created your NetBeans Project your application class should contain the following executable code: package addlinenumbers; public class AddLineNumbers f public static void main(String[I args)f Write the code for the main class as indicated below: package addlinenumbers; /* Import the Scanner class and all classes from java.io*/ // Your code here public class AddLineNumbers public static void main( String [ args ) /* Declare variable identifiers to handle text data input from the file and count/increment the linenumber * //Your code here /* Start try block */ // Your code hereExplanation / Answer
dataInput.txt
public class Hello
{
public static void main(String [] args )
{
System.out.println("Hello");
}
}
