Tutorial Flat File Generic Save/Load

FlatFile.java:

Code:JAVA

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.Serializable;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;
 
import org.bukkit.util.io.BukkitObjectInputStream;
import org.bukkit.util.io.BukkitObjectOutputStream;
 
public class FlatFile {
    public static <T extends Serializable> boolean save(String filePath, T object) {
        try {
            BukkitObjectOutputStream out = new BukkitObjectOutputStream(new GZIPOutputStream(new FileOutputStream(filePath)));
            out.writeObject(object);
            out.close();
            return true;
        } catch (IOException e) {
            return false;
        }
    }
    public static <T extends Serializable> T load(String filePath){
        try {
            BukkitObjectInputStream in = new BukkitObjectInputStream(new GZIPInputStream(new FileInputStream(filePath)));
            T object = (T) in.readObject();
            in.close();
            return object;
        } catch (ClassNotFoundException | IOException e) {
            return null;
        }
    }
}

Usage:

Code:JAVA

// Objects you are saving and loading must implement/extend Serializable or a Compilation Error will occur
    FlatFile.save(plugin.getDataFolder() + "/fileName.extension", objectToSave);
// You must ensure that the data stored in the file being loaded corresponds to the object being loaded back or a Runtime Error will occur
    objectToLoad = FlatFile.load(plugin.getDataFolder() + "/fileName.extension");
