Java is a object oriented language. In this language, the object is the main element. It can contain methods, variables and constructors. Variables can be of different types such as primitive types (int, long etc.), object types (String, int etc.), primitive & object reference types (int&str etc.) and user defined types (Object, Name etc.).

In a thread, a piece of code is running in parallel to other threads. One thread is called the main thread or simply the main thread. The main thread of a java program is defined by the statement public static void main. The main thread has control over all of the threads that are part of its java program.

The Java program above is an example of a Socket Programming Java test. You will be required to make Java applications on the client/server sides that can transmit data across the network using the Socket Programming APIs of the Java programming language. The code above illustrates a basic Network Programming program where a client sends some text strings to the server and the server prints them on a new line. In this example, the test question will be to solve, declare and code the server program.
