Original description

Hi all.
I don't find any documentation about support concurrent programming Java . 
May I can write code with use concurrent programming Java?
For example:

package com.action;

import com.model.Task;
import com.orientechnologies.orient.core.db.object.ODatabaseObjectTx;

public class TaskThread implements Runnable {
    private ODatabaseObjectTx db;
    private String parentId;

    public TaskThread(ODatabaseObjectTx db, String parentId) {
        this.db = db;
        this.parentId = parentId;
    }

    public void run() {
        createTask(parentId);
    }

    private void createTask(String parentId) {
        int currentId = TestThread.getCurrentId();
        Task task = new Task(String.valueOf(currentId), "task_"+currentId, parentId);
        System.out.println(Thread.currentThread() + " : id: " + task.getId() + "\tname: " + task.getName() + "\tparent: " + task.getParent());
        db.save(task);
    }
}


package com.action;

import com.orientechnologies.orient.core.db.object.ODatabaseObjectTx;

public class TestThread {
    private static int currectId = 0;
     private final static String URL = "local:/home/pitbull/projects/ThreadOriendDB/store/db1/trackstudio40";

    public static synchronized int getCurrentId() {
        return ++currectId;
    }

    public static void main(String[] args) {
        ODatabaseObjectTx db = new ODatabaseObjectTx(URL).open("admin", "admin");
        for (int i=0;i!=1000000;++i) {
            new Thread(new TaskThread(db, "1")).start();
        }
    }
}
