The Important Basics of Java Programming, Every Programmer Should Know

These days one of the most widely used programming languages is Java. This is because Java is not only fast but also very secure and reliable. So Java finds many uses and applications, including in desktop-based programs to supercomputers etc.

But before you become a Java expert, and before you get a good Java programmer’s jobs, as an aspiring developer, you must first know the fundamentals of this language. In this article I have formulated the list of basics that each Java Programmer must know.

  1. Java Environment:

There are following three main components of the Java Programming Environment:

  • JDK
  • JRE
  • JVM
  1. Basic Syntax of Java:

As is true with every other programming language, Java has a distinct set of rules that you need to define and work on its modules. We highly recommend that you read them, learn them and get a short but thorough overview of this syntax.

  1. Data Types in Java:

In Java each variable is associated with a data type. And for each data type, a different amount of memory is allocated. This is then used for specific operations.

  1. Java Variables:

A memory location is basically a variable, which is the most basic unit of storage in a program.

  1. Java Keywords:

Java Keywords are words used for internal processes or to show predefined actions. And so, such words are reserved. Programmers cannot use them as variable names. If these keywords are used, the user will end up getting a compiler error.

  1. Java Operators:

Operators are the foundation of any programming language. Java would be incomplete if it didn’t have operators. In short operators can be defined as symbols that help perform specific logical or mathematical calculations.

  1. Java Loops:

Loops are used to execute some repetitive tasks, until the conditions governing the task become true (or as otherwise defined in the loop execution condition). Java supports three ways of loop execution. Each one provides a similar (basic) function. But they differ in their syntax and the ‘checking time’ of the governing condition.
