This article will go over five Java developer beginner level of coding interview questions from our website. These will be basic coding questions, and in the next few weeks will have more advanced coding interview questions you can check out as well. Let's get started. How would you create an arraylist that will hold a list of string variables? This question will require you to read a code example that demonstrates utilization of my arraylist using a Java class. Try to lay the foundation of your answer by explaining your example of how the arraylist would be used, avoid any complicated code blocks that will require importing more libraries and using methods that are not mandatory for your example. Keep in mind that the interviewer is aware that you don't have access to the Java documentation or the help of a search engine to keep your code simple. And to create an arraylist in a Java program, we will first have to import the arraylist library found in the Java detail package.

在本节中，我们将介绍我们网站上的五个Java开发人员初级水平的编码面试问题。这些将是基本的编码问题，在接下来的几周里，将会有更高级的编码面试问题，你也可以查看。我们开始吧。如何创建保存字符串变量列表的ArrayList？这个问题需要你读一段代码。演示使用Java类使用我的ArrayList的示例。尝试通过解释如何使用ArrayList的示例来为您的答案奠定基础，避免任何复杂的代码块，这些代码块将需要导入更多的库，并使用对您的示例来说不是强制性的方法。请记住，面试官知道您无法访问Java文档或搜索引擎的帮助，以保持代码简单。要在Java程序中创建ArrayList，我们首先必须导入Java细节包中的ArrayList库。

Next, we create an arraylist object using the realist constructor that takes as an argument, the data type of our arraylist elements. The following is a good example, demonstrating this concept. How would you use a constructor to initialize a Java object? This question is open-ended, which means you need to either explain in your own words how to utilize a constructor or provide a code example. The strategy that is riskfree in this question is to combine both, start your answer with a small introduction, then follow up with a code example, how to utilize a constructor to initialize a Java object to initialize a Java object and constructor can be used to define the attributes that this object will take.

接下来，我们使用现实主义构造函数创建一个ArrayList对象，该构造函数将ArrayList元素的数据类型作为参数。下面是一个很好的例子，演示了这个概念。如何使用构造函数来初始化Java对象？这个问题是开放式的，这意味着您需要用自己的话解释如何使用构造函数，或者提供一个代码示例。在这个问题中，无风险的策略是将两者结合起来，以一个小的介绍开始你的答案，然后是一个代码示例，如何利用构造函数来初始化Java对象来初始化Java对象，构造函数可用于定义该对象将采用的属性。

For example, let's say our goal is to initialize an object called obj this object doesn't have any attributes that need initialization. Also, the object can be initialized using a class called demo class. This example be demonstrated as follows. How do you define the starting point of your Java program known as the main method in this question? Your job would be simply to provide a code example of the main method. In other words, you can try to serve your answer with a small introduction about the main method and what makes it important to the flow of your Java program. However, the end goal is write down the syntax of the main method, expect a follow up question that will test your understanding of every element in the main method.

例如，假设我们的目标是初始化一个名为obj的对象，该对象没有任何需要初始化的属性。此外，还可以使用名为Demo Class的类来初始化该对象。这一实施例被证明如下。如何定义Java程序的起始点，即本问题中的main方法？您的工作只是提供Main方法的代码示例。换句话说，您可以尝试通过简单介绍main方法以及它对Java程序流的重要性来回答问题。然而，最终目标是写下main方法的语法，预计后续问题将测试您对main方法中每个元素的理解。

In Java programming. The main method is a starting point of every program, and it is the first method executed when you run a Java program. The syntax of the main method can be as coded as follows. How would you create a job class? This question will require you to read a code example that demonstrates the creation of a job class, avoid any complicated code blocks that will require debugging and double checking your code. In other words, try to write your Java class in the simplest way possible. Indeed, this is not a question to showcase long code blocks and complex class creation. How would you formulate a try catch block in Java? This question will require you to write a code example that demonstrates utilization of try to catch to deal with exceptions and Java errors. Your job is right, a code example, demonstrating the use case of try catch in a simple, the other effective way. What approach is? Ready? Tried catch for an out of bound rate error.

在Java编程中。main方法是每个程序的起点，它是运行Java程序时执行的第一个方法。main方法的语法可以编码如下。如何创建作业类？这个问题将要求您阅读一个代码示例，演示如何创建一个作业类，避免任何复杂的代码块，这将需要调试和双重检查您的代码。换句话说，尽量以最简单的方式编写Java类。实际上，这不是一个展示长代码块和复杂类创建的问题。如何在Java中设计try_catch块？这个问题要求您编写一个代码示例，演示如何使用try to catch来处理异常和Java错误。你的工作是正确的，一个代码示例，以另一种简单有效的方式演示了try catch的用例。方法是什么？准备好了？已尝试捕捉超出界限的速率错误。
