Java interview questions code#

This byte code isn't platform specific and hence can be fed to any platform. Java is compiled in byte code which is the intermediate language between the source code and the machine code. Question 15) What gives Java 'write once and run anywhere' nature ? This characteristic is known as Write Once Run Anywhere. Java interpreter is changed depending upon the platform. The Java programs need to be written just once, which can be run on different platforms without making changes in the Java program. Question 14) What is Write Once Run Anywhere characteristic of Java ? Actually this Java interpreter is known as the Java Virtual Machine (JVM). Program written in Java are compiled into Java Byte code, which is then interpretedР”В«y a special Java Interpreter for a specific platform. It hides the underlying operating system from Java applications. The Java Virtual Machine is an abstract machine designed to be implemented on the top of existing processors. Question 13) What do you understand by JVM ? Language Java byte code is exactly the same on every platform. The Java byte code looks a lot like machine language, but unlike machine Instead it produces a special format called byte code. Contrary to ordinary compilers, the Java compiler does not produce native executable code for a Machine code is called native executable code. In ordinary compilation, the source code is converted to a machine code, which is dependent upon the machine or the platform. Question 12) How is ordinary compilation process different from Java compilation ? Interactive, dynamic and secure applications on networked computer systems.

The Java platform is a new software platform designed to deliver and run highly

Used to refer to some combination of hardware and system software. Like any other programming language, we can use Java to write or create various types of computer applications. Question 11) How can you say that Java is both a programming language and a platform ? The property of decomposing a system into a set of cohesive and loosely coupled modules.

Inheritance is the capability of one class of things to inherit the capabilities or properties from more detail Question 9) What is inheritance ? In a different way (depending upon its class) to the same message. It is a property by which the several different objects respond It is the ability for a message or data to be processed in more than one form. Question 7) How base class and derived class are interrelated ?Р”Р„ derived class has nearly all the properties of base class but the reverse of it is not true. And a base class is a class whose properties are inherited byР”Вerived class. Question 6) What is the difference between base class and derived class ?Р”Р„ derived class is a class that inherits properties by some other class. Question 5) How Abstraction and Encapsulation are interrelated ?Р”В®ncapsulation is the way of implementing abstraction. Question 4) What do you mean by Abstraction and Encapsulation ?Р”Р„bstraction is the act of representing essential features without including the background details.Р”Р„nd encapsulation is the way of combiningР”В«oth data and the functions that operate on the data under a single unit. It represents an entity thatР”В¬an store data and its associated functions.Р”Р„ class is a group of objects that share common properties and relationships. Question 3) What is the difference between an object and a class ?Р”Р„n object is an identifiable entity with some characteristics and behaviour. Grouping of procedures with related data, the procedural programming approach still applies. In modular programming, a set of related procedures with the data they manipulate is combined under a until called module. Question 2) How is modular programming approach different from procedural programming approach ? This approachР”В®mphasizes on the 'doing' rather than the 'data'. The programming approach that focuses on the procedures for the solution of a problem is known as procedural programming paradigm. Question 1) What do you understand by procedural programming paradigm ? Here we listed only those Java questions, thatР”В¬an be frequently asked in the Java interview or Java practical examination. This can also helps you to feel better in Java Interview (Java Practical Examination Hall).
