The import com mongodb client mongoclient cannot be resolved

I am new to MongoDB and I want to establish connection with my mongod server. But I get the error MongoClient cannot be resolved to a type I have included external Jar into my project but still cannot fix the error

Here is my code I think there is no error in my code but I have included wrong JAR file in my project

import com.mongodb.*;
import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

public class Dining {

public static void main[String[] args] {
Lock forks[] = new ReentrantLock[5];

try {
    MongoClient mongoClient = new  MongoClient["mongo"];
    System.out.println["Connection to mongodb successful."];
    DB db = mongoClient.getDB[ "mydb" ];
    System.out.println["Database 'mydb' created."];
    DBCollection coll = db.createCollection["mycol", null];
    System.out.println["Collection 'mycol' created."];
} catch [Exception e] {
    // TODO Auto-generated catch block
    e.printStackTrace[];
}
