Question. Number one. What are the key elements of the Java programming language? This is the type of question, and your view will use to begin the conversation, learn more about your background and collect Information they can use throughout interview. This question also provides you the opportunity to direct interview towards a subject area that you are familiar with and comfortable responding to questions about. Throughout the interview, keep your answers brief and to the .. This will encourage the interviewer to ask followup questions about the same topic or move on to a new subject.

第一个问题，Java编程语言的关键要素是什么？对于这种类型问题，你的观点将用来展开话题，面试官可以了解更多关于你的背景，并在面试过程中收集他们可以用来提问。这个问题还为您提供了直接针对您熟悉的主题领域进行面试的机会，并且您可以轻松地回答相关问题。在整个面试过程中，你的回答要简明扼要。这将鼓励面试官就同一主题提出后续问题，或转移到一个新的主题。

There are several key features of the job of programming language. First, it is simple to learn next. Java is somewhat object oriented and enables programmers to manage their code using objects. Several other key features of Java includes portability, platform independence, security, and the large library of code available to programmers.

编程语言的工作有几个关键特征。首先，下一步学习很简单。Java在某种程度上是面向对象的，它使程序员能够使用对象来管理他们的代码。Java的其他几个关键特性包括可移植性、跨平台、安全性和程序员可用的大型代码库。

Question number two, within Java, what are the differences between path and class path variables? This is a common format of a technical question, technical questions, ask you about concepts or items related to the work you do. They sometimes ask you to compare similar concepts or to describe how they are used. When answering technical questions using this format, you should first define the terms you were asked about. You then either compare them or describe how they use. You may provide an example if it helps illustrate your answer. Have in class path are environmental variables, which the operating system uses to locate executables. The less locates the executors in a directory location, which is defined by these variables. The difference between a path and classpath variable is that a class path is very specific to Java, and can be defined as a directory is a file, jar file, or another type of variable.

第二个问题，在Java中，路径变量和类路径变量有什么区别？这是技术问题的常见格式，技术问题，询问您与您所做的工作相关的概念或项目。他们有时会要求你比较类似的概念或描述它们的使用方法。在使用此格式回答技术问题时，您应首先定义所询问的术语。然后，您可以比较它们或描述它们如何使用。你可以提供一个例子，如果它有助于说明你的答案。类 Class PATH中的是环境变量，操作系统使用这些变量来定位可执行文件。LESS将执行器定位在由这些变量定义的目录位置中。路径和类路径变量之间的区别在于，类路径是Java特有的，可以定义为目录、文件、JAR文件或其他类型的变量。

Question number three, can you discuss what a static import is and what the pitfalls of using this are? This technical question, as you to first find the concept and then describe some features of its use. Static import is the process of importing the class and the method variable with the class name from another class. This makes the class available. The pitfall using this methodology is that it may cause confusion if it is overused and thereby trigger the program to malfunction.

第三个问题，你能讨论一下什么是静态导入以及使用它的陷阱是什么吗？这个技术问题，作为你首先找到的概念，然后描述它的使用的一些功能。静态导入是从另一个类导入类和带有类名的方法变量的过程。这将使类可用。使用这种方法的缺陷是，如果它被过度使用，可能会引起混乱，从而触发程序故障。

Question number four, programming in Java. Can you have an empty catch block? This is an example of an operational question. Operational questions, evaluate specific elements, used in your job, like technical questions, answers, operational questions should be brief into the point. You should also anticipate follow up questions if the interviewer needs additional Information or wants to explore the topic in more detail, while you can use empty catch block, while programming in Java, it is not advised the problem this creates involves bugging the program at the empty catch block or to catch an exception. There will not be any Information about the exception, finding issue with no Information, and the law can be very time consuming.

第四个问题，Java编程。你能有一个空的捕捉块吗？这是一个操作问题的例子。操作型问题，评价具体要素，用在你的工作中，像技术型问题，回答操作型问题时要简明扼要。如果访问者需要额外的信息或想要更详细地探讨该主题，您还应该预测后续问题，虽然您可以使用空catch块，但在Java编程时，不建议这样做所产生的问题涉及在空catch块处调试程序或捕获异常。不会有任何关于例外的信息，在没有信息的情况下发现问题，并且法律可能非常耗时。

Question number five, can you discuss the importance of the main method in Java? As a job developer? You can anticipate that most of the questions will be asked during interview will be technical. The best way to prepare for these is to review the concept using Java programming and understand the processes, libraries, tools, methodologies, job developers, use. Being familiar with these will help you prepare for the questions you are likely to be asked. The main method, as it is used in Java, provides programmers with an entry point for any code they're writing. It defines a syntax to run a program within the Java language. It also enables Java to access the code without initialize in a class. The value contained within the parentheses is an array of string related to run time arguments.

第五个问题，你能讨论一下Java中main方法的重要性吗？作为一个工作开发者？你可以预料到在面试中被问到的大多数问题都是技术性的。准备这些的最好方法是使用Java编程来回顾概念，并了解流程、库、工具、方法、工作开发人员的使用。熟悉这些将有助于你为可能被问到的问题做好准备。Java中使用的main方法为程序员编写的任何代码提供了入口点。它定义了在Java语言中运行程序的语法。它还使Java能够在不初始化类的情况下访问代码。括号中包含的值是与运行时参数相关的字符串数组。
