Explanation / Answer

Hi,

Here is the corrected answer.

package com.example.package; // Please use your own package
import java.nio.file.*;
import java.nio.file.attribute.*;
import java.io.IOException;
public class DebugThirteen1
{
public static void main(String[] args)
{

try
{
   Path file1 =
       Paths.get("C:\Java\Chapter.13\\DebugData1.txt");
       Path file2 =
       Paths.get("C:\Java\Chapter.13\\DebugData2.txt");// Please use the path of the file from where you want to access it.
BasicFileAttributes attr1 =
Files.readAttributes(file1, BasicFileAttributes.class);
System.out.println("File: " + file1.getFileName());
System.out.println("Creation time " + attr1.creationTime());
System.out.println("Last modified time " + attr1.lastModifiedTime());
System.out.println("Size " + attr1.size());
BasicFileAttributes attr2 =
Files.readAttributes(file2, BasicFileAttributes.class);
System.out.println(" File: " + file2.getFileName());
System.out.println("Creation time " + attr2.creationTime());
System.out.println("Last modified time " + attr2.lastModifiedTime());
System.out.println("Size " + attr2.size());
if(attr1.creationTime().compareTo(attr1.creationTime()) > 0)
System.out.println(" " + file1.getFileName()+ " was created earlier");
else
System.out.println(" " + file1.getFileName() + " was not created earlier");
if(attr1.size() > attr2.size())
System.out.println(file1.getFileName() + " is larger ");
else
System.out.println(file2.getFileName() + " is not larger");
}
catch(IOException e)
{
System.out.println("IO Exception "+e.getMessage());
}
}
}

Output is as follow: Please make the changes in the program as per your requirements
