Java was originally developed as an implementation of a programming language that would compile and complete its directive functions regardless of platform and language version. It was developed by James Gosling, a software developer employed by Sun Microsystems in June of 1991, whom released the first version of Java in 1995. The language is designed …
Traversing a list A linear list can be traversed in two ways In order traversal Reverse order traversal In order Traversal To traverse the linear linked list, we walk the list using the pointers, and process each element until we reach the last element. .cf { font-family: Lucida Console; font-size: 9pt; color: black; background: white; …
The conversion from basic to user defined data types can be done using constructors. Consider the following constructor: .cf { font-family: Lucida Console; font-size: 9pt; color: black; background: white; } .cl { margin: 0px; } .cb1 { color: green; } .cb2 { color: blue; } .cb3 { color: maroon; } String :: String(char *a) …
Java does not directly support constants. However, a static final variable is effectively a constant. The static modifier causes the variable to be available without loading an instance of the class where it is defined. The final modifier causes the variable to be unchangeable. Ex: public static final int FOUNDING_YEAR = 2001; Naming Standards for …
In this method, a function fn() is applied to each key. The result of this function determines into which of the several sub-files the record is to be placed. The function should have the property that x <= y, fn (x) <= fn (y). Such a function is called order preserving. Thus all of the …
This FAQ answer is an excerpt from SNIPPETS by Bob Stout. Don't hold your breath. Think about it… For a decompiler to work properly, either 1) every compiler would have to generate substantially identical code, even with full optimization turned on, or 2) it would have to recognize the individual output of every compiler's code …
The term algorithm is used in a variety of fields, including mathematics, computer programming, and linguistics. Its most well-accepted definition is something that consists of a finite list of instructions (which are well defined) that can be used to accomplish a task. Basically, when an algorithm is given some initial state, it will use the …
SDLC (Systems Development Life Cycle) is the process of creating or modifying existing systems and the models and methodologies that are used in the process. In the fields of software engineering and information systems, SDLC denotes a framework of methodologies aimed at the creation of an information/software system, i.e. the software development process. SDLC covers …
Computer users sometimes need to uninstall Java, for various reasons. In case of upgrading Java, you needn’t remove the previous version of Java. Instead, you can simply run the executable of the newer Java version and the upgrade will automatically happen. However if you wish to uninstall Java, below are the methods for different platforms. …
