Communications link failure when trying to connect to the database

Question

I want to insert data to my database using JDBC, so the first step is to connect to it:

try {
        Class.forName("com.mysql.jdbc.Driver");
    } catch (ClassNotFoundException e) {
        System.out.println("Where is your MySQL JDBC Driver?");
        e.printStackTrace();
        return;
    }

    System.out.println("MySQL JDBC Driver Registered!");
    Connection connection = null;

    try {
        connection = (Connection) DriverManager
        .getConnection("jdbc:mysql://localhost:3306/fruits","root", "halo");
        System.out.println("Connecting...");

    } catch (SQLException e) {
        System.out.println("Connection Failed! Check output console");
        e.printStackTrace();
        return;
    }

    if (connection != null) {
        System.out.println("You made it, take control your database now!");
    } else {
        System.out.println("Failed to make connection!");
    }

The problem is I'm getting this error:

MySQL JDBC Driver Registered!
Connection Failed! Check output console
com.mysql.jdbc.CommunicationsException: Communications link failure due to underlying exception:
