Java as a programming language Java is an Object oriented application programming language developed by Sun Microsystems. Java is a very powerful general-purpose programming language.

Master Java In A Week

Master Java Programming Language in a week. This tutorial is good for beginners in Java and it will teach you the basics and advanced concepts of Java programming Language. Java is versatile, platform independent programming language for developing software for desktop, servers, mobile applications and embedded devices. Performance of the Java application is very high and it is highly extensible.

 

     

Here is the list of tutorials of Java for making you perfect in Java programming language in a week.

  1. Starting Java

    1. Introduction to the Java Programming Language
       
    2. Java as a programming language
      Java is an Object oriented application programming language developed by Sun Microsystems. Java is a very powerful general-purpose programming language.

    3. Java as an Object Oriented Language
      In this section, we will discuss the OOPs concepts along with  fundamentals  used to develop the java applications and programs.
       

    4. Applications and Applets
      Now a days, Java is widely used for applications and applets. The code for the application in object format resides on the user's machine and is executed by a run-time interpreter.
       

    5. Peculiarities of Java
      The concept of Write-once-run-anywhere (known as the Platform independent) is one of the important key feature of java language that makes java as the most powerful language.
        

  2. Java Tools

    1. Compilers
      To commence with Java programming, we must know the significance of Java Compiler. When we write any program in a text editor like Notepad, we use Java compiler to compile it.

    2. Interpreter
      We can run Java on most platforms provided a platform must has a Java interpreter. That is why Java applications are platform independent. Java interpreter translates the Java bytecode into the code that can be understood by the Operating System.
       

    3. Debugger
      Java debugger helps in finding and the fixing of bugs in Java language programs. The Java debugger is denoted as jdb. It works like a command-line debugger for Java classes. 
       

    4. Header file generator
      Firstly, The native methods are in pure C code, not C++. The function prototypes are in an object-oriented form of C which are being provided by javah , but they are still not object methods.
       

    5. JavaDoc
      Sun Microsystems has provided a computer software tool known as Javadoc. This tool is used to generate API documentation into HTML format from Java source code. It is interesting to know that Javadoc is the industry standard for documenting Java classes.
       

    6. Applet Viewer 
      Applet viewer is a command line program to run Java applets. It is included in the SDK. It helps you to test an applet before you run it in a browser. Before going any further, lets see what an applet is?
       

  3. Java Empowered Browsers
    Java language is the most powerful language and is widely used in the web application. So the current versions of most of the web browser are made java enabled. Mostly used java enabled web browsers are:

    1. Internet Explorer 

    2. Netscape

    3. HotJava

    4. Safari

    5. Firefox 1.0.4

    6. Mozilla 1.6
       

  4. Installing Java ...
    Before getting started developing an application the developer must ensure that he/she is going to develop an application by using  the best tools. The combination of two features Platform Independent and Object Oriented makes the java powerful to build the flexible application.

    1. Let's start with the Java Development Kit

    2. JDK Installation

    3. JDK Installation on Sun Solaris

    4. JDK Installation on Windows 95 and Windows NT

    5. JDK installation on Apple Macintosh system 7.5

    6. Testing the installation

    7. Exploring the java Developer's kit

    8. Distributing the Java Virtual Machine

    9. Other Development Environment

    10. Summary
          

  5. To Commence with Java ... ( Learn Java in a day)

    • 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
      Data type defines a set of permitted values on which the legal operations can be performed. In java, all the variables needs to be declared first i.e. before using a particular variable, it must be declared in the program for the memory allocation process.
            

    • 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.
       

    • Operators and Expressions
      Operators are such symbols that perform some operations on one or more operands. Operators are used to manipulate primitive data types. Once we declare and initialize the variables, we can use operators to perform certain tasks like assigning a value, adding the numbers etc.

    1. Simple Assignment Operators

    2. Arithmetic Operators

    3. Unary Operators

    4. Equality and Relational Operators

    5. Conditional (Logical) Operators

    6. Bitwise and Bit Shift Operators

    7. Type Operators  

      

    • Operator Precedence 
      In Java, Operator Precedence is an evaluation order in which the operators within an expression are evaluated on the priority bases. Operators with a higher precedence are applied before operators with a lower precedence. 
         

  6. Java Syntax ...

    1. Classes 
      There are some kind of errors that might occur during the execution of the program. An exception is an event that occurs and  interrupts the normal flow of instructions. That is exceptions are objects that store the information about the occurrence of errors.
       

    2. Hello world (First java program)
      Java is a high level programming language and it is used to develop the robust application. Java application program is platform independent and can be run on any operating System
           

    3. Under Standing the HelloWorld Program
      Class is the building block in Java, each and every methods & variable exists within the class or object. (instance of program is called object ). The public word specifies the accessibility of the class.
        

    4. Data types, Variables
      The type of value that a variable can hold is called data type. When we declare a variable we need to specify the  type of value it will hold along with the name of the variable
      .

      • Primitive Data Types

      •  Literals

      •  Variables

      •  Declaring and Assigning values to Variables 
             

  7. 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.

    1.  Introduction to Arrays

    2.  Structure of Arrays

    3.  Array Declaration

    4.  Array Initialization

    5. Array Usage

    6.  Multi-dimensional arrays

    7. Two-dimensional arrays

    8. Copying Arrays
        

  8. Control Statements ...

    1. if
      To start with controlling statements in Java, lets have a recap over the control statements in C++. You must be familiar with the if-then statements in C++. The if-then statement is the most simpler form of control flow statement. 
           

    2. for
      In the world of Java programming, the for loop has made the life much more easier. It is used to execute a block of code continuously to accomplish a particular condition. For statement consists of tree parts i.e. initialization, condition, and iteration.
           

    3. switch
      Sometimes it becomes cumbersome to write lengthy programs using if and if-else statements. To avoid this we can use Switch statements in Java. The switch statement is used to select multiple alternative execution paths.
           

    4. while and do-while  
      Lets try to find out what a while statement does. In a simpler language, the while statement continually executes a block of statements while a particular condition is true. 
           

    5. Break and Continue Statements
      Sometimes we use Jumping Statements in Java. Using for, while and do-while loops is not always the right idea to use because they are cumbersome to read. Using jumping statements like break and continue it is easier to jump out of loops to control other areas of program flow.
        

  9. Class, Object and Methods

    1. Class

    2. Object

    3. Constructor

    4. Constructor Overloading
       

  10. 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.

    1. Simple Inheritance

    2. Multilevel Inheritance

    3.  Java does not support multiple Inheritance

    4.  super keyword
       

  11. Abstract Methods and Classes
    While going through the java language programming you have learned so many times the word abstract. In java programming language the word abstract is used with methods and classes.

    1. Abstract Method

    2. Abstract Class
       

  12. Packages
    Package is a mechanism for organizing a group of related files in the same directory. In a computer system, we organize files into different directories according to their functionality, usability and category.

    1. Package categories in Java

    2. Create Your Own Package

    3. How to import a package

    4. Create Subpackages
       

  13. Interface in Java
    In this section we will learn about Interface and Marker Interfaces in Java. This tutorial will clarify you questions "What is marker Interface?" and "Why use Marker Interface?" and "difference between abstract class and the interface"

  14. Exception Handling
    Exception, that means exceptional errors. Actually exceptions are used for handling errors in programs that occurs during the program execution. During the program execution if any error occurs and you want to print your own message..... 
     

  15. Input and Output
    The Java I/O means Java Input/Output and is a part of java.io package. This package has a InputStream and OutputStream. Java InputStream is  for reading the stream, byte stream and array of byte stream.

    1. Introduction

    2. Read Text from Standard IO

    3. Filter Files in Java

    4. Java read file line by line

    5. Create File in Java

    6. Copying one file to another

    7. Serializing an Object in Java

    8. De-serializing an Object in java

     

  16. Applets
    Applet is java program that can be embedded into HTML pages. Java applets runs on the java enables web browsers such as mozila and internet explorer. Applet is designed to run remotely on the client browser, so there are some restrictions on it.

    1. Introduction

    2. Advantages of Applet

    3. Disadvantages of Java Applet

    4. Life Cycle of Applet

    5. Creating First Applet Example

    6. Passing Parameter in Java Applet
