...on. These groups can be conveniently represented as elements of arrays. The declaration of array includes the type of array that is the type of value we are going to store in it, the array name and maximum number of elements. Examples: short val[200]; val[12] = 5; Declaration & Data Types Arrays have the same data types as variables, i.e., short, long, float etc. They are similar to variables: they can either be declared global or local. They are declared by the given syntax: Datatype array_name [dimensions] = {element1,element2,….,element} The declaration form of one-dimensional array is Data_type array_name [size]; The following declares an array called ‘numbers’ to hold 5 integers and sets the first and last elements. C arrays are always indexed from 0. So the first integer in ‘numbers’ array is numbers[0] and the last is numbers[4]. int numbers [5]; numbers [0] = 1; // set first element numbers [4] = 5; This array contains 5 elements. Any...

Cook. Manufactured in the United States of America. Preface You will find this book to be somewhat unusual. Most computer science texts will begin with a section on the history of computers and then with a flurry of definitions that are just “so many words” to the average student. My approach with Blue Pelican Java is to first give the student some experience upon which to hang the definitions that come later, and consequently, make them more meaningful. This book does have a history section in Appendix S and plenty of definitions later when the student is ready for them. If you will look at Lesson 1, you will see that we go right to work and write a program the very first day. The student will not understand several things about that first program, yet he can immediately make the computer do something useful. This work ethic is typical of the remainder of the book. Rest assured that full understanding...

...JMaster list of Java interview questions - 115 questions By admin | July 18, 2005 115 questions total, not for the weak. Covers everything from basics to JDBC connectivity, AWT and JSP. 1. What is the difference between procedural and object-oriented programs?- a) In procedural program, programming logic follows certain procedures and the instructions are executed one after another. In OOP program, unit of program is object, which is nothing but combination of data and code. b) In procedural program, data is exposed to the whole program whereas in OOPs program, it is accessible with in the object and which in turn assures the security of the code. 2. What are Encapsulation, Inheritance and Polymorphism?- Encapsulation is the mechanism that binds together code and data it manipulates and keeps both safe from outside interference and misuse. Inheritance is the process by which one object acquires the properties of another object. Polymorphism is the feature that allows one interface to be used for general class actions. 3. What is the difference between Assignment and Initialization?- Assignment can be done as many times as desired whereas initialization can be done only once. 4. What is OOPs?- Object oriented programming organizes a program around its data, i. e. , objects and a set of well defined interfaces to that data. An object-oriented program can be characterized as data controlling 5. access to code. What are Class, Constructor...
