Determine file creation date in Java

I have a file named abc.txt which is created by my application in c:. Now I have to write logic in such way that if file is created within 1 hour timeframe then I have to print:

file is created within 1 hour itself

and if file is created more than 1 hour before then to print the statement:

It has been more then 1 hour the file is created

How can I achieve this?

java.io.File.lastModified() should suit your needs.

@user1726942 I think you could try by yourself. `lastModified()` returns *the time that the file denoted by this abstract pathname was last modified*. From that, writing an algorithm that checks whether the file has been modified during the last hour or not is not so hard. – sp00m Oct 23 '12 at 08:55

Below is the code

File f = new File("path of file");
Date now = new Date();
Date filedate = new Date(f.lastModified());
if((now.getTime()-filedate.getTime())>60000){
    System.out.println("It has been more then 1 hour the file is created");
}else{
    System.out.println("file is created within 1 hour itself");
}
