Advance Java Programming

The Java Database Connectivity (JDBC)
The Java Database Connectivity (JDBC) API is the industry standard for database-independent connectivity between the Java programming language and a wide range of databases SQL databases and other tabular data sources, such as spreadsheets or flat files.

RMI

The Java Remote Method Invocation Application Programming Interface (API), that performs the object-oriented equivalent of remote procedure calls (RPC).

1. The original implementation depends on Java Virtual Machine (JVM) class representation mechanisms and it thus only supports making calls from one JVM to another. The protocol underlying this Java-only implementation is known as Java Remote Method Protocol (JRMP).

2.In order to support code running in a non-JVM context, a CORBA version was later developed.

Socket Programming

• In computing, network programming, essentially identical to socket programming or client-server programming, involves writing computer programs that communicate with other programs across a computer network.
• The client and server processes together form a distributed system. The communication between the client and server process may either be connection-oriented (such as an established TCP virtual circuit or session), or connectionless (based on UDP datagrams).
• … and many more like applet, awt, swing, event that will help you to develop GUI Application.
