The garbage collector Rather than forcing you to keep up with memory allocation or use a third-party library to do so , the Java platform provides memory management out of the box. When your Java application creates an object instance at runtime, the JVM automatically allocates memory space for that object from the heap— a pool of memory set aside for your program to use. The Java garbage collector runs in the background, keeping track of which objects the application no longer needs and reclaiming memory from them.
Garbage collection is one of the essential features of Java platform performance.
The Java Development Kit When you download a Java Development Kit JDK , you get — in addition to the compiler and other tools — a complete class library of prebuilt utilities that help you accomplish most common application-development tasks. The JRE is available for multiple platforms. Although you can use these tools to develop your applications, most developers appreciate the additional functionality, task management, and visual interface of an IDE.
Eclipse is a popular open source IDE for Java development. Eclipse handles basic tasks, such as code compilation and debugging, so that you can focus on writing and testing code.
In addition, you can use Eclipse to organize source code files into projects, compile and test those projects, and store project files in any number of source repositories.
If you download one of the Eclipse bundles, it will come with the JDK already. Agree to the license terms for the version you want to download. Choose the download that matches your operating system and chip architecture. Windows Save the file to your hard drive when prompted.
When the download is complete, run the install program. OS X When the download is complete, double-click it to mount it. Run the install program. You do not get to choose where the JDK is installed. You now have a Java environment on your computer. Install Eclipse Browse to the Eclipse packages downloads page. Under Download Links on the right side, choose your platform the site might already have sniffed out your OS type.
Click the mirror you want to download from; then, save the file to your hard drive. When the download finishes, open the file and run the installation program, accepting the defaults. To set up your Eclipse development environment: Launch Eclipse from your local hard disk. When asked which workspace you want to open, choose the default. Close the Welcome to Eclipse window. The welcome window is displayed each time you enter a new workspace.
Figure 1 shows this selection highlighted in the Eclipse setup window for the JRE. Figure 1. Eclipse is now set up and ready for you to create projects, and compile and run Java code. The next section familiarizes you with Eclipse. This section is a brief hands-on introduction to using Eclipse for Java development.
The Eclipse development environment The Eclipse development environment has four main components: Workspace Perspectives Views The primary unit of organization in Eclipse is the workspace.
A workspace contains all of your projects. A perspective is a way of looking at each project hence the name , and within a perspective are one or more views.
Figure 2 shows the Java perspective, which is the default perspective for Eclipse. You see this perspective when you start Eclipse. Figure 2.
Eclipse Java perspective The Java perspective contains the tools that you need to begin writing Java applications. Each tabbed window shown in Figure 2 is a view for the Java perspective. Package Explorer and Outline are two particularly useful views.
The Eclipse environment is highly configurable. Each view is dockable, so you can move it around in the Java perspective and place it where you want it.
For now, though, stick with the default perspective and view setup. Figure 3. New Java Project wizard Enter Tutorial as the project name and use the workspace location that you opened when you opened Eclipse. Though this is the tried and tested approach and working well from a long time, it can be improved. He outlines both benefits and drawbacks of Microservices and explains to them how to implement them using popular frameworks like DropWizard and Spring Boot.
This free Java book is full of useful examples. Filled with a lot of samples but non-trivial examples of implementing different data structures e.
Since data structure and algorithm are very important for any Java programmer and quite a common topic in Java interview, it is an absolute must to have a strong command in both. If you are preparing for Java job interviews then you can also take a look at some of my favorite algorithm and data structures questions, it may help in your preparation.
