# Java Comments
To comprehend any programming language, there are several kind of comments which are used. These comments are advantageous in the sense that they make the programmer feel convenient to grasp the logic of the program.

the sense that they make the programmer feel convenient to grasp the logic
of the program.
- Java Keywords
There are few keywords in Java programming language.
Remember, we cannot use these keywords as identifiers in the program. The
keywords "const" and "goto" are reserved though, they are not being currently
- Java Data Types
Java programming language is a language in which all
the variables must be declared first and then to be used i.e. to
specify the name and the type of the variable. This specifies that Java is a
strongly-typed programming language
By literal we mean any number, text, or other
information that represents a value. This means what you type is what you
get. We will use literals in addition to variables in Java statement. While
writing a source code as a character sequence, we can specify any value as a
literal such as an integer.
In this section you will be introduced to the concept
of Arrays in Java Programming language. You will learn how the Array class
in java helps the programmer to organize the same type of data into
easily manageable format.
Operators are symbols that performs some operations on
one or more then one operands. Once we declare and initialize variables, we
can use operators to perform certain tasks like addition, subtraction etc.
- Controlling your program
We all know that the execution of the statements in a
program takes place from top to bottom. We will learn how the different
kinds of statement have different effects in looping like decision-making
statements (if-then, if-then-else, switch), the looping statements (for,
while, do-while), and the branching statements (break, continue, return) in
Java programming language.
- Java Classes
In this section you will be introduced to some essential classes in Java
like Exceptions, Basic I/O, Concurrency etc.
- Class Inheritance
To know the concept of inheritance clearly you must
have the idea of class and its features like methods, data members, access
controls, constructors, keywords this, super etc.
You have been introduced to the contents of Java
language providing a great amount of information. Perhaps it would be a bit
arduous to grasp the whole lot of things at one go. However, the
implementation of these little basics will make you a substantial
