# 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.
Java Language
- 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.
- 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 used.
- 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
- Literals
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.
- Arrays
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
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.
- Summary
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 programmer.
