如何通过Oracle的Java认证-开发人员实用指南 (How to Pass Oracle’s Java Certifications — a Practical Guide for Developers)

A Java certification is highly regarded in the IT Industry and provides a Java developer with recognition worldwide. It helps you to find a better job, get a better salary, and even a better raise or bonus at your current job.

Java认证在IT行业中享有很高的声誉，并为Java开发人员提供了全球认可的认证。它可以帮助您找到一份更好的工作，获得更高的薪水，甚至在您目前的工作中获得更高的加薪或奖金。

That’s why thousands of Java developers try to become certified every year, but success is not easy in this exam.

这就是为什么每年都有成千上万的Java开发人员尝试获得认证的原因，但是在此考试中取得成功并不容易。

Oracle’s Java Certification has a tough passing percentage, close to 65% for both OCAJP (the Oracle Certified Associate Java Programmer) and OCPJP (the Oracle Certified Professional Java Programmer).

Oracle的Java认证的合格率很难， OCAJP (Oracle认证的Java程序员)和OCPJP (Oracle的Java专业认证)都接近65％ 。

You need in-depth knowledge of the Java language and API to succeed in the exam.

您需要具备Java语言和API的深入知识才能通过考试。

As a note, preparing for OCPJP is not very different from OCAJP, though you have to use resources that are focused only on OCPJP. You also need to cover more topics and more in-depth because OCPJP 8 is certainly a tough nut to crack.

需要注意的是，为OCPJP做准备与OCAJP并没有太大区别，尽管您必须使用仅专注于OCPJP的资源。您还需要涵盖更多主题和更深入的内容，因为OCPJP 8当然是一个难以克服的难题。

In order to prepare well and get a high score, here are some tips I am going to share. These tips have helped me in the past to score more than 90% on the certifications.

为了做好准备并获得高分，我将分享一些技巧。这些技巧过去帮助我获得了90％以上的认证分数。

So, without wasting any more time, here are my five tips to prepare well for the OCAJP and OCPJP exams.

因此，在不浪费更多时间的情况下，这是我为OCAJP和OCPJP考试做好准备的五个提示。

1.每天编码 (1. Code Every Day)

There is no substitute for coding. You must code daily to develop a coding sense, which will help you to read code given in the real exam.

不能替代编码。您必须每天编写代码以发展编码意识，这将帮助您阅读真实考试中给出的代码。

In the case of OCPJP, it becomes even more important because attention to detail is required to understand each coding question before you select options.

对于OCPJP ，它变得尤为重要，因为在选择选项之前，需要注意细节才能理解每个编码问题。

2.参加一个好的课程 (2. Join a Good Course)

In my opinion, online courses are one of the best ways to learn a new technology in a short period of time, and that also holds true for preparing a certification exam like Oracle’s Java certification.

我认为，在线课程是在短时间内学习新技术的最佳方法之一，并且对于准备诸如Oracle Java认证之类的认证考试也同样适用。

They are the second best way, just next to a personal instructor or classroom training. You learn actively from experienced professionals who have gone through that path and know exactly where the breakers are and where the road is bumpy.

它们是仅次于私人教练或课堂培训的第二好的方法。您会从经验丰富的专业人员那里积极学习，他们已经走过了那条道路，并且确切地知道了断路器的位置和道路的崎bump不平。

When I prepared for my Java certification some 10 years ago, books were the only way, particularly the Khalid Mughal book, but now you have a lot more books and courses to help you out.

大约十年前，当我准备Java认证时，书是唯一的方法，尤其是Khalid Mughal的书，但是现在您有更多的书和课程可以帮助您。

3.阅读一本好书 (3. Read a Good Study Book)

There is no better companion than a good study book if you are preparing for Java certifications.

如果您正在准备Java认证，没有比最好的学习书更好的伴侣了。

They cover all the exam topics, give practice questions at the end of the chapter, and share a lot of exam-specific tips that you don’t find in any normal Java book.

它们涵盖了所有考试主题，在本章末尾提出了练习题，并分享了许多在任何普通Java书籍中都找不到的特定于考试的技巧。

There are a lot of study guides available in the market, but if you are preparing for OCAJP 7 or OCAJP 8 you can take a look at these resources to find a good study guide.

市场上有很多学习指南，但是如果您准备使用OCAJP 7或OCAJP 8 ，则可以阅读这些资源以找到一份好的学习指南。

4.选择一个好的考试模拟器 (4. Choose a Good Exam Simulator)

After choosing a good book or study guide, the next thing you need is a good exam simulator. This is must if you want to score high but not required if you just aim for passing the exam.

选择好书或学习指南后，接下来需要的是一门好考试模拟器。如果您想获得高分，这是必须的，但如果您只是想通过考试，则不需要。

The exam simulators will help you to develop speed and accuracy required to complete all questions in 2.5 hours.

考试模拟器将帮助您提高在2.5小时内完成所有问题所需的速度和准确性。

I suggest that you keep doing mock tests until you score 80% on a consistent basis before going for the real exam.

我建议您继续进行模拟测试，直到您获得稳定的分数达到80％，然后再进行真正的考试。

Here are some of my recommendations for exam simulators:

这是我对考试模拟器的一些建议：

David Mayer’s Practice Test
大卫·梅耶(David Mayer)的实践测试

5.定期参加论坛 (5. Regularly Participate on Forums)
