Java Training: A Popular Programming Language with a Difference
Like any other language in the world, Java language has its own rules of syntax and structure. Additionally, it follows a particular programming paradigm. Java language supports OOP or object oriented programming. This is a C language derivative so it has much in common with the syntax rules of this programming language. Code blocks are, for example, are modularized into methods and braces delimit them. Variables are declared prior to their usage.
-
Java Training comes in big packages
Java is a language which structurally starts with packages. The package is basically the namespace mechanism. Going further into this, classes are contained within packages. There are different components within the classes such as methods, variables, constants and more.
-
Java Compiler composes the bytecode
When you program for the Java platform, source code is written in Java file and then compiled. Compiler checks the code against the syntax rules of the language known as the bytecode. Bytecode is set of instructions targeted on JVM or Java Virtual Machine. Java compilers offer from others which write out instructions.
-
What is the JVM?
Java Virtual Machine reads and interprets .class files and executes the instructions of the program on native hardware platform. JVM interprets the bytecode much like assembly language instruction is interpreted by the CPU. JVM is written for a specific platform.
-
Java…the write once, run anywhere principle
JVM runs on the “write on, read anywhere” principle and the code can also run on a chipset for which the JVM implementation is available. For major platforms such as Windows and Linux, subsets of Java language have been implemented.
-
Java Training…memory management out of the box
Rather than keeping up with memory allocation or using third party libraries, Java provides memory management out of the box. This means that when the Java application creates an object instance within the run time, memory space for the object is allocated by the JVM automatically from a heap- pool of memory set aside for programs to use.
The Java garbage collector, called so because it keeps track of objects that are no longer needed by apps and reclaims memory from them,is a handy tool for implicit memory management as it does not require any memory handling code. This is one of the essential features of Java platform performance.
-
Java Development Kit…prebuilt utilities for accomplishing tasks
A JDK A OR Java Development Kit gets a complete class of library of prebuilt utilities that help in accomplishing common app development tasks in addition to the compiler and other tools. Java Runtime Environment or JRE is inclusive of the JVM, code libraries and components needed for running programs written in Java language. JRE can be used for varied platforms and freely redistributed with applications.
JDK consists of a set of command line tools for compiling as well as running the Java code including a complete copy of JRE. Though these tools can be used to develop apps, additional functionality and task management as well as unique interface of an IDE is considered far better. Java perspective contains tools needed to start writing the applications in this programming language.
Java Training: Some Basic Concepts
Java language is object oriented mostly. This means that it defers from structural programming. While structured programming paradigm is highly data oriented, object oriented language such as Java combines data and program instructions into objects. So, what is an object? Java Training is a self contained entity with specific attributes and behavior.
In object oriented languages like Java, data and program logic are combined whereby parent objects serve as structural basis for complex child objects. In Java Training terminology, objects talk to others by sending messages called method calls. In object oriented application, program code specifies the activities among objects to perform tasks within given app domain. Object is a discrete entity that has necessary dependencies on other objects.
State is an important concept in object oriented programming represented by the value of its attributes. The defining principles of OOP are encapsulation, inheritance and polymorphism. Object’s discreteness is the principle of encapsulation at work. This is one of the most powerful features of this programming language. Through the property of inheritance, specialized classes without additional code can copy attributes and behaviors of source classes that they specialize. Polymorphism is a concept whereby objects that belong to the same branch of a hierarchy can sent the same message and manifest this behavior in a different way.
Java Training is not purely object oriented however. Not everything in the language is an object, as against purely object oriented languages such as Smalltalk. Java provides tools needed to follow OOP principles and some discipline in code writing is essential. Much like any other programming language, Java designates certain words that are recognized as special by the compiler. The following are the list of reserved words in Java Training:
| assert | abstract | boolean | break |
| byte | case | catch | char |
| class | const | continue | default |
| do | double | else | enum |
| extends | final | finally | float |
| for | goto | if | implements |
| import | instance | int | interface |
| long | native | new | package |
| private | protected | public | return |
| short | static | strictfp | super |
| switch | synchronized | this | throws |
| throw | transient | try | void |
| volatile | while |
Class defines the basic structure of the object and serves as a blueprint for the discrete entity comprising attributes and behavior. Names are chosen for classes and packages provide a good way to create complex applications with discrete units of functionality. The class’s methods define its behavior. A constructor method is used to create an instance of a class. Various other methods can be used for any aspect of application behavior. Combination of structural elements in the definition of a method is known as its signature. To instantiate a class, construction has to be specified. Methods can be named and there are static as well as instance methods. While instance methods depend on the state of a specific object for their behavior, static methods are called class methods as their behavior is not dependent on a single object state.
Objectives of Java Training:
Java in our Java Training is more than a programming language….it is a technology. Java Training has the following aims and objectives:
- It seeks to eliminate difficulties of other languages such as pointer arithmetic and memory management that affects the strength of the code

What are the pre-requisites of learning Java Training?
Java Training has absolutely zero perquisites for learning the language. Much like other programming languages, Java Training has its own syntax for declaring local variables or functions called methods. Counter based loops, while-do loops, do-while loops and for loops et al are some of the many ways to execute a tasks several times over. Java Training introduces fresh though streams to experienced programmers.
Java Training learning is easier if you have some idea of OOP because Java’s main strength comes from this attribute. You need to think logically, be able to write code and imagine in blocks to define classes as well as read and understand technical language as well as notation. Knowledge of computer memory and pattern based thinking are added advantages for Java Training.
Java Training can be learnt without knowing any other programming languages. Prior knowledge is not needed to commence programming. Java Training a great first language to learn and if you want to short circuit the process, learning Python or any other good scripting language is a good step forward.
