What is the open() method?

The open() method is a method of the Connector class. It is used to create a connection of a MIDlet to a Web server. There are three versions of the open() method. They are as follows:

• static Connection open(String connectionstring): This version takes only a String parameter that specifies the type of the connection to be established, such as http, socket, etc., and the address of a Web server.
• static Connection open(String connectionstring, int mode): This version, in addition to the String parameter, requires an int parameter, which specifies one of the three connector modes. These modes are READ, WRITE, and READ_WRITE.
• static Connector.open(String connectionstring, int mode, boolean timeout): This method takes a third Boolean parameter, which specifies whether or not the application can handle a timeout exception. A timeout exception occurs when an application cannot establish a network connection within a stipulated time.
