Best Ways To Get Through To Your JAVA TUTORIALS



Let’s discuss the java tutorials, Basically, java tutorials mostly are designed for students and professionals. In any language, there are some fundamentals that we all need to know before we can write even the most elementary programs. Java fundamentals are essential for java programs. The keywords, identifiers, literals, operators, separators are all the features of java. We shall also know about the class and objects before we can get into the further details of java. So along with these, we shall also acquire some ideas about the variables and expressions. Let us 1st proceed with the java character set.


Java character set is a set of valid characters that a language can recognize. A character represents any letter, digit or any other sign. Java uses the Unicode character set. Unicode is a 2-byte character codee4 set that has characters representing almost all the characters in almost all human alphabets and writing systems around the world including Hindi, English, Chinese, Malayalam and many more. We can refer to a particular Unicode character by using the escape sequence followed by the 4-digit hexadecimal number.

They are the words that convey a special meaning to the language compiler. These are reserved for special purposes and must not be used as a normal identifier name.


They are the fundamental building blocks of a program and are used as the general terminology for the names given to the different parts of the program viz. variables, objects, classes, functions, and arrays, etc.


They are often referred to as the constant and are the data items that are fixed data values. Java allows different types of literals like integer, floating, Boolean, character, string, and null.


The ASCII are the separators. Punctuations are also referred to as the separators.


They are the symbol that initiates an action. Few tokens are considered as the operators which help us to denote either conditional or other operations.

The java has 2 types of data types:

1. Primitive and 2. Reference data type.

Now let us get some idea about the java statements:
A statement is a single command that is executed by the java interpreter. By default, the java interpreter runs one statement after the other in the order in which they are written. Java offers many statements, including the simple, compound, program flow, and control statements.


A single statement is the one that has only 1 statement which might be of assignment expressions or ++ or – or method calls or object creation expression, etc.


A block statement is a group of 0 or more single statements enclosed between the 2 balanced braces.


Programs not only store data but also manipulate the data in terms of consolidation, rearranging and modifying data. To perform their manipulative miracles, programs need tools for performing repetitive actions and for making decisions. Java, of course, provides the tools by proving us the statements for doing so. Such statements are called control structures or program control statements.

They allow choosing the set of instructions for the execution depending upon the expression’s truth value. Java provides 2 types of such statements and they are: if and switch.


they test the particular condition. If the condition is true, then a course of action is followed else the opposite.


java provides a multiple branch selection statement that is known as a switch. The selection statement successively checks the value of an expression against a list of integer or character constant. When the match is found then the associated statements are carried out.


Java (TUTORIALS) is a popular 3rd generation programming language, which can be used to do any of the thousand things that computer software can do. With the features its offers, java has become one of the languages of choice for the intranet applications. Java plays an important role in the proper functioning of many software-based devices attached to the network. The kind of functionality that java offers have contributed to a lot more in java programs. Java programs are compiled, and their byte codes are produced. The byte codes are always exactly the same irrespective of the computer system they are to execute upon. Java byte code is the machine instruction for the java processor chip called the java virtual machine. It is independent of the computer it has to run upon. These were some of the basic properties and features one must know in order to proceed with java. This language was originally named as Oak before it was coming to be known as java.
