![]() For example, Java does not allow direct access to the operating system, which makes it more difficult for attackers to exploit security vulnerabilities. This is because Java has built-in security features that help to protect applications from malicious code. Safety: Java is a safer language than C++. This means that Java programmers do not need to worry about allocating and freeing memory, while C++ programmers need to be careful to manage memory correctly to avoid memory leaks. Memory management: Java uses automatic memory management, while C++ requires manual memory management. This means that Java code can run on any platform that has a Java virtual machine (JVM), while C++ code can only run on the platform that it was compiled for. Platform independence: Java is a platform-independent language, while C++ is a platform-dependent language. Java and C++ are both object-oriented programming languages, but they have some key differences. It is also a relatively easy language to learn, making it a good choice for beginners. Java is a powerful and versatile language that is well-suited for a wide range of tasks. Java is one of the most popular programming languages in the world, and is used in a wide variety of applications, including: It was released in May 1995 as a core component of Sun Microsystems’ Java platform. Java was originally developed by James Gosling at Sun Microsystems. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. It is a general-purpose programming language intended to let programmers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. ![]() Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. Our expert team will get back to you at the earliest.īasic Java Interview Questions for Freshers Q1. In case you attended any Java interview recently, or have additional questions beyond what we covered, we encourage you to post them in our QnA Forum. Here’s a definitive list of top Java Interview Questions that will guarantee a breeze-through to the next level. The output indicates that the MySQL driver is deployed to a location in the GlassFish server.As a Java professional, it is essential to know the right buzzwords, learn the right technologies and prepare the right answers to commonly asked Java Programming Interview Questions. You can view progress in the IDE’s Output window (Ctrl-4 ⌘-4 on Mac). In the IDE’s Projects window, choose Deploy from the right-click menu of the project node. If you do not see the driver JAR file, perform the following step.ĭeploy your project to the server. Because you should have already deployed the IFPWAFCAD project to the server, you should see the mysql-connector-java-5.1.6-bin.jar file. On your computer, navigate to the GlassFish server installation directory and drill into the domains > domain1 > lib subfolder. As shown in the image above, the driver JAR file should be located within domain1, which is the default domain created upon installing the GlassFish server. ![]() Each instance runs applications in a unique domain, and the Domain Name field indicates the name of the domain your server is using. ![]() When you connect to the GlassFish server in the IDE, you are actually connecting to an instance of the application server. Before you close the Servers manager, make a note of the path indicated in the Domains folder text field.
