Java using modified time and Store and read objects and URI reference programs

Get file last modified time

package com.java2novice.files;

 import java.io.File;

 public class MyFileLastModified

{

        public static void main(String a[])

       {

        File file = new File("MyProp.xml");

        System.out.println(file.lastModified());

    }

 }

Store and read objects from a file

Get file URI reference

package com.java2novice.files;

import java.io.File;

public class MyFileUrl

{  

    public static void main(String a[])

     {

        File f = new File("C:/TestForm.txt");

        System.out.println(f.toURI());

    }

}
