How to import Mongo Libraries in Java Project

I used mongo-java-driver version 3.7.1 & 3.8.2 in java build path. Still, I am getting the error "the import com.mongo.MongoClient cannot be resolved".

Connection.class 

import java.net.UnknownHostException;
import com.mongodb.MongoClient;
import com.mongodb.DBCollection;
import com.mongodb.DBCursor;
import com.mongodb.DBObject
import com.mongodb.Mongo;
import com.mongodb.Db;

public class MongoClass {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try {
            MongoClient mongoClient = new MongoClient("localhost",27017);
            System.out.println("connection successfully established");
        }
        catch(UnknownHostException e) {
            e.printStackTrace();
        }

    }
}

According to the MongoDB Java sample, you can start building this way :

import com.mongodb.MongoClientSettings;
import com.mongodb.MongoCredential;
import com.mongodb.ServerAddress;
import com.mongodb.client.MongoClient;
import com.mongodb.client.MongoClients;
import com.mongodb.client.MongoDatabase;

import java.util.Arrays;

public class MongoClass {

private MongoDatabase database = null;

public static void main(String[] args) {
    MongoCredential credential = MongoCredential.createCredential("username", "database", "password".toCharArray());

    MongoClientSettings.Builder builder = MongoClientSettings.builder();

    builder.applicationName("myapp");

    builder.credential(credential);

    builder.applyToClusterSettings((b) ->
            b.hosts(Arrays.asList(new ServerAddress("localhost", 27017))));

    MongoClient mongoClient = MongoClients.create(builder.build());

    database = mongoClient.getDatabase("MYDATABASE_1");

    mongoClient.close();
}
