Windows Java File lock when referencing existing file in constructor?

Suppose I do the following in java for a process that stays open:

import java.io.File;
import java.util.Date;
public class LogHolder {
    public static void main(String[] args) {
        File file1 = new File("myLogFile.log");        
        while (true) {
            System.out.println("Running " + new Date());
        }
    }
}

Have I locked this file in a way that ot开发者_如何学Cher windows processes can't write to the log file?

This might help you: FileLock.

No, you haven't locked the file. Here's how the Java documentation summarizes the purpose of java.io.File:

An abstract representation of file and directory pathnames

(In other words, new File() doesn't even open the file.)
