# Using Objects

Once objects are created we can access thier members using the dot operator, (.).

## Accessing Field Object Members

The general form of accessing fields is

objectReference.fieldName


To access the url field we can use the following

socket.url = "http://chat.peruzal.co.za";


We can get the value of the field,

String apiUrl = socket.url;


## Accessing Object Methods

The general form of accessing methods is as follows

objectReference.methodName(arguments);


We can call the connect method from the Socket class as follows :

socket.connect();


We can call the send method which takes one argument as follows :

socket.send("Howdy!");


We can also pass in multiple parameters separated by commas. For the send method, declared as follows

public class Socket {
void send(String username, String message){

}
}


We can call the method as follows :

socket.send("joseph", "Java is awesome!");
