  Methods for Stopping a Thread     private volatile Thread thrd; public void stop() { thrd = null; } public void run() { Thread thisThread = Thread.currentThread(); while (thrd == thisThread) { try { thisThread.sleep(interval); } catch (InterruptedException e){ } repaint(); } }   The volatile keyword is used to ensure prompt communication between threads.    A field may be declared as volatile , in which case a thread must reconcile its working copy of the field with the master copy every time it accesses the variable. Moreover, operations on the master copies of one or more volatile variables on behalf of a thread are performed by the main memory in exactly the order that the thread requested.”

1. Why java does not support multiple inheritance ? Answer :- To say why java doesn't support inheritance directly like c++ should be the diamond problem faced by c++,(Diamond problem is an ambiguity that arises when two classes B and C inherit from A, and class D inherits from both B and C.

Collections in Java Introduction to Collections Framework The Collections Framework provides a well defined set of interfaces and classes for storing and manipulating the groups of data into a single unit. Introduction to Collections Framework Collections Framework: The Collections Framework provides a well-designed set of interfaces and classes for storing and manipulating the groups of data into a single unit. The collections framework is a unified architecture which is used to represent and manipulate collections. The framework allows the collections to get manipulated independently, additionally it reduces the programming efforts and increases performance. It includes implementation of interfaces and algorithms. Basically it is a unified architecture that consists the following collections: Interfaces: These are the abstract data types that represent collections. With the help of interfaces we manipulate collections independently. A hierarchy is generally formed ...

                           Data Warehousing A data warehouse consists of a computer database responsible for the collection and storage of information for a specific organization. This collection of information is then used to manage information efficiently and analyze the collected data. Although data warehouses vary in overall design, majority of them are subject oriented, meaning that the stored information is connected to objects or events that occur in reality. The data provided by the data warehouse for analysis provides information on a specific subject, rather than the functions of the company and is collected from varying sources into one unit having time-variant. Data warehousing professionals build and maintain critical warehouse infrastructure to support business and assist business executives in making smart business decisions. Warehous...
