Study Material For Java Programming Pdf

[Julian Gladyshev]

Pleasenote, that this is a legacy course. It is no longer possible to gain ECTS credits for completing the course. The course content is also no longer updated or maintained. You can find our current Python course here

During this course, you will learn the basics of computer programming, along with algorithms and object-oriented programming through the Java programming language. The course includes comprehensive materials and plenty of programming exercises - all of which are tested using our automatic testing service Test My Code.

The course is split up into two individual courses: Java Programming I and Java Programming II. Each course consists of seven parts, each with its own exercise set. Completing a single part takes approximately 5-20 hours, and we recommend reserving at least 10 hours per part, depending on prior skills with computers.

This book is intended to be used for a first course in computer programming. No prior experience with programming should be necessary in order to use this book. But this book is intended to be used with a course that teaches more than computer programming; it is intended to be used with a course that teaches Computer Science. The distinction is subtle, but important.

The author(s) believe that a breadth-first approach is the best way to introduce the concepts of Computer Science to students. Rather than isolate topics in courses (bits and bytes in a computer organization course; formal grammars and languages in a theory course; lists, sets, and maps in a data structures course; etc) we believe that topics should be introduced in a brief and simple manner at the starting level. Elaboration on these topics should occur in subsequent courses. This breadth-first approach allows the student to build on existing knowledge and retain a greater proportion of the material.

These days, the idea a physical dictionary is pretty old-fashioned. Consulting a physical book to learn the meaning of a word or phrase makes no sense when a simple Google search will give you all the information you need.

Most programming languages use hashes to ensure the uniqueness of keys and make storage and retrieval of values more efficient. A HashMap in Java puts all of that together to allow programmers to store key-value pairs by hashing their keys upon insertion and retrieval.

Our StudyGuide class begins pretty humbly. We start by initializing a final static HashMap called studyGuide as our study guide. All the keys of studyGuide, representing our concepts, will be of the String type while the values, the meanings of our concepts, will be of our custom Meaning type.

There, we call the put() instance method of our HashMap five times, putting a concept and its meaning in studyGuide each time. This method ends by calling updatePossiblePoints() to set the possible points, static possiblePoints, obtainable by a user:

At the top of the while loop, we must store the Set of keys in studyGuide in a constant by calling its keySet() instance method so that we can iterate over it. For each key, we get its value by calling the get() instance method of studyGuide and passing it the key. The value returned and stored in currentConceptMeaning is a Meaning instance representing the meaning of a concept. So long as the currentConceptMeaning is not null, we let the user take a guess at what they think it is. If the userInputMatches() instance method of currentConceptMeaning returns true, we call its markUserGotCorrect() instance method to set its gotCorrect instance field to true and increment userPoints because the user provided the correct meaning for the concept.

Java is a powerful and widely-used programming language that has revolutionized the world of software development.

Our core Java programming tutorial is designed for students and working professionals. Java is an object-oriented, class-based, concurrent, secured and general-purpose computer-programming language. It is a widely used robust technology.

Java was developed by Sun Microsystems (which is now the subsidiary of Oracle) in the year 1995. James Gosling is known as the father of Java. Before Java, its name was Oak. Since Oak was already a registered company, so James Gosling and his team changed the name from Oak to Java.

Standalone applications are also known as desktop applications or window-based applications. These are traditional software that we need to install on every machine. Examples of standalone application are Media player, antivirus, etc. AWT and Swing are used in Java for creating standalone applications.

An application that runs on the server side and creates a dynamic page is called a web application. Currently, Servlet, JSP, Struts, Spring, Hibernate, JSF, etc. technologies are used for creating web applications in Java.

An application that is distributed in nature, such as banking applications, etc. is called an enterprise application. It has advantages like high-level security, load balancing, and clustering. In Java, EJB is used for creating enterprise applications.

It is a Java programming platform. It includes Java programming APIs such as java.lang, java.io, java.net, java.util, java.sql, java.math etc. It includes core topics like OOPs, String, Regex, Exception, Inner classes, Multithreading, I/O Stream, Networking, AWT, Swing, Reflection, Collection, etc.

It is an enterprise platform that is mainly used to develop web and enterprise applications. It is built on top of the Java SE platform. It includes topics like Servlet, JSP, Web Services, EJB, JPA, etc.

As you write your next programs, learn how to use indenting, it sounds like such a simple thing that has no impact at all on what the program does or how it will be compiled. It also has nothing to do with what bytecodes get generated. Yet, it can be critical to writing successful computer programs, especially as those programs become more complex. The same can be said of commenting. There is excellent material on both those topics in the readings.

When writing programs, it is important to create meaningful names (identifiers) for your classes, methods, and variables. Recognize that some identifiers are reserved to the language itself. Those cannot be used to name anything else. Programmer identifiers must be unique but are meaningless to the compiler. Still, they are essential to programming, from the human perspective. (Calling something xxx is no different from calling that same thing yyy, from the compiler's perspective.) Indenting, commenting, and meaningful identifiers all have to do with human-readable code. Such code is essential to debugging, finding and fixing syntax errors or logic errors in a program. Readable code is also important to maintenance, modification, and evolution. Do not be caught in the trap of thinking you are smart if nobody can understand the code you write. That is a mark of a non-professional and is easily spotted by technical team leaders. If you take that route, do not be surprised when you find yourself on the outer edge of the plate as the economy goes through its cycles. As a cycle brings on a decline, the plate shrinks. Non-Professionals fall off the plate (get laid off) at that point. Your job becomes insecure and you become less employable.

We spoke about Integrated Developer Environments (IDEs) and advanced text editors earlier. Those can help a great deal with a language's syntax. For example, they can identify matching syntaxual pairs such as ( ) , , and [ ]. These details are easy to miss as one translates human expressions of processes into something the computer can understand (a particular computer language). Let the computer help you with the details so that you can concentrate on what you are trying to accomplish.

Packages are composed of several classes, interfaces, and other formal types. These make up callable libraries, some within the Java language itself, while others are written by third parties for specific purposes.

Java packages organize classes into unique namespaces. Classes in the same package have access to private and protected members of all classes in that package. Packages can contain the following types: classes, interfaces, enumerations, and annotations. Programmers can group classes and interfaces according to various criteria depending on the system being created.

Java interfaces expand beyond what other languages provide. They are very useful for describing abstract data types. Interfaces offer method signatures, but not method contents. Classes implement interfaces by declaring the interface in an implements clause. It is in the class description that method bodies are provided for interfaces.
