Arrays

  • An uninitialised Object that is an array element will be set to null by default. If we write:

String s[][] = new String[2][2];
System.out.println(s[1][1]);
System.out.println(s[1][2]);

The second call to println because all arrays start from 0, so an array with an element of size 2 has elements 0 and 1 but no element 2.

Rich Client based UI technologies- A Comparison of Thick Client UI tools

Rich Client v/s Thin Client Software developers face many difficult decisions when building new applications, not the least of which is graphical user interface. There are various graphical user interface technologies used, but broadly they can be classified as Rich Client User interfaces and the thin client or web based user interfaces. To understand them better let us look at the history of rich and thin clients. While the Rich client GUI applications would support high quality end-user experience with features such a drag-and-drop, perspectives, customization, high speed local processing; it has had a traditional disadvantage of high deployment and upgrade costs. It was becoming highly difficult and costly to deploy and upgrade these applications. Then came the thin clients or the Web based applications. Thin clients solved many of the deployment and upgrade problems, but that was not without a cost, the cost was in terms of functionality and capability. Thin clients, based on

OSS and BSS Systems

Image
OSS (Operational Support Systems) Software (occasionally hardware) applications that support back-office activities which operate a telco’s network, provision and maintain customer services. OSS is traditionally used by network planners, operations, architects, support, and engineering teams in the service provider. Increasingly product managers and senior staff under the CTO or COO may also use or rely on OSS to some extent. BSS (Business Support Systems) Software applications that support customer-facing activities. Billing, order management, customer relationship management, call centre automation, are all BSS applications. BSS may also encompass the customer-facing veneer of OSS application such as trouble-ticketing and service assurance – these are back-office activities but initiated directly by contact with the customer. OSS/BSS Structure Communication between OSS and BSS Apart from service assurance activities being cross-OSS-BSS processes, there are as m
