The Oracle 1Z0-808 exam is aimed at the professionals pursuing the Oracle Certified Associate (OCA) Java SE 8 Programmer certification. This credential is designed to build the foundational knowledge of Java as well as equip the specialists with skills for the everyday job roleof a Java SE Programmer. In fact, this Oracle certificate is the first of the two critical steps to validating the high-level skills required to become a qualified Java developer.
To obtain this OCA certification,the candidatesareadvised to go through the beginner & intermediate Java SE 8 training to gain hands-on experience before taking the Oracle 1Z0-808: Java SE 8 Programmer Itest. The professional-level (OCP) certificate requires Java SE 8 Programmer II. For the purpose of this article, the focus will be on the first exam – Oracle 1Z0-808. Let’s look at its details.
Thoseindividuals who want to earn OCA must pass the PrepAway Oracle 1z0-061 – 1z0-808 – 1z0-071 – 1z0-809 – 1z0-062 Amazon AWS A+ TOGAF 200-150 PDF Pass4sure before receiving their credential. The exam includes 70 questions, and the studentswill have 150 minutes to answer them. The format you should expect is multiple-choice questions. It is important to mention that the test is validated against the Java SE 8 release, and the passing score is 65%. Before the registration process, you are required to pay the fee of $245. It is for a single try, which means if you have to retake your exam, you will be required to pay again.
There are specific subjects that make up the content of Oracle 1Z0-808. The test takers must develop competence in the scope of these topics before attempting the exam to ensure their success. According to Oracle, the objectives that you have to study before attempting this certification test are reviewed on the official website. Let’s get right into them.
- Understanding Java Basics
This covers fundamental components of Java features. The questions on this topic will cover the specificareas, such as definitions of scope of variables; definitions of Java class structure; creation of executable Java applications using a major method; and running a Java program from the command line as well as producing console output. It also comes with importing other Java packages to enable them accessible in coding. The candidates will also be required to contrast and compare different features and components of Java, such as platform independence,encapsulation, and object orientation.
- Using Decision Constructs &Operators
The questions from this topic will evaluate the ability of the applicants to use Java operators and parenthesis to override operator precedence. It will also evaluate their capacity for testing equality between Strings & other objects utilizing == and equals (). The learnerswill also have to demonstrate their ability to utilize switch statements as well as create if, if/else, and ternary constructs.
- Using Loop Constructs
The individuals will need to demonstrate the capacity to create & use while loops; create & use do/while loops; create & use for loops like enhanced for a loop; evaluate loop constructs.
- Working with Inheritance
The cert bolt applicants will be tested on their ability to describe inheritance as well as the benefits. They will also be evaluated based on their ability to develop code that uses polymorphism and code that overrides methods, as well as distinguish between the type of reference and the type of object. You should also know a thing or two about the usage of super & this to access constructors and objects, and use abstract classes & interfaces. Your ability to determine when casting is required will also be evaluated.
- Working with Special Classes from Java API
You will be required to demonstrate competence in manipulating data, creating & manipulating Strings, calendar data using different features of Java. The test takers also need to show the ability to write simple Lambda expressions and use ArrayList of a specific type. They should also be able to import statements and assume missing package; unintended line breaks; descriptive comments; code fragments; and no file/directory path names for different classes.
- Working with Types of Java Data
This topic will evaluate one’s ability to declare & initialize variables; distinguish between object and primitive reference variables; describe object’s lifecycle; understand how to read/write to object fields; develop code using wrapper classes.
- Creating and Using Arrays
The candidates will be evaluated on their ability to declare, initialize, instantiate & use multi-dimensional and one-dimensional arrays.
- Working with Methods & Encapsulation
Your ability to create methods with return argumentsand values as well as the capability to apply a static keyword to methods and fields will be evaluated. Additionally, the examinees will have to demonstrate the skills in creating and overloading constructors; distinguishing between user-defined and default constructors. Their competence in applying access modifiers and encapsulation principles to class will also be tested. The applicants should also be able to determine the impact on object references and primitive values when passed into methods that alter the values.
- Handling Exceptions
Those individuals who want to pass Oracle 1Z0-808should know about the capability to distinguish among unchecked exceptions, checked exceptions, &errors. They will also be required to create a try-catch block and decide how the exceptions change standard program flow. Their ability to describe the benefits of exception handling and create & invoke the method that throws an exception will also be evaluated. It is also important that the learners are able to identify regular exception classes, such as ArrayIndexOutOfBoundsException NullPointerException, ArithmeticException, ClassCastException, etc.
Oracle recommends some training courses to equip the test takers with the required skills and knowledge. However, this is optional. You can find the details of these courses on the official page. In addition to the officially recommended study materials, you should also consider some resources from other platforms to help you prepare for your certification exam. For example, you can check the bundle from the PrepAway website. It has a comprehensive training portfolio for Oracle 1Z0-808verified by the experts and designed to guarantee your success in the test.
It doesn’t matter what certification exam you need to pass; eachsuch test requires a lot of effort.That is why preparing with all your heart and soul will greatly increase your chances of passing Oracle 1Z0-808. Good luck!
