September 18th, 2009Numeric values having no decimal parts are called integer literals. These values can be expressed in decimal, octal, and hexadecimal forms. By default, integer literals are in decimal form. The decimal form contains a sequence of decimal digits (0 to 9), the octal form contains a sequence of octal digits (0 to 7) prefixed by 0 (zero), whereas the hexadecimal form contains a sequence of hexadecimal digits (0 to 9, a to f) prefixed by 0x or 0X. In the hexadecimal form, the characters (a to f) may be in uppercase or lowercase.

August 14th, 2009Fundamental Object-Oriented Concepts
JDBC
August 14th, 2009The introduction of the Java language is required before introducing the concept of JDBC. Java is an object-oriented programming language. It incorporates all the objected-oriented concepts such as polymorphism, abstraction, encapsulation, etc. Java is a platform independent language because it can run on different operating systems. Java syntactically resembles C and C++, but it is simpler than the two, as it does not contain pointers and multiple inheritance. Both pointers and multiple inheritance seem complex to the application developer.
