Oracle Java Certificates
The IT certificates from Oracle for Java serve as proof of extensive knowledge in Java - Programming for the Java Platform, Standard Edition , Java Platform, Micro Edition and Java Platform, Enterprise Edition . They are built on each other in the form of a certification path and, like all Oracle certificates, are divided into four levels:
- Oracle Certified Associate (OCA)
- Oracle Certified Professional (OCP)
- Oracle Certified Expert (OCE)
- Oracle Certified Master (OCM)
The order in which the certificates can be obtained does not depend on the levels, for example the "Oracle Certified Master Java EE6 Enterprise Architect" certificate can be achieved without obtaining a previous certificate.
For the most part, the certificates do not correspond to the current Java versions (currently JSE 8 and JEE 7 ) and in some cases already relate to versions that have reached their "End of Life" (ie are no longer maintained by Oracle).
The individual certificates
Holders of a certificate completed under an older version of the Java platform have the option of performing an upgrade test that only covers changed or new language features and accordingly includes fewer questions. However, the upgrade is not a prerequisite for acquiring advanced certificates; For example, an “Oracle Certified Professional Java Programmer” certificate, which was filed under platform version 6, can be used to acquire a further certificate for the Java 7 platform.
Most certifications can be taken for different versions of Java.
Oracle Certified Associate Java SE8 Programmer
The IT certificate Oracle Certified Associate Java Programmer (formerly Sun Certified Associate for the Java Platform ) is used to detect entry knowledge in Java - programming . Since version 7 it has been a prerequisite for the Oracle Certified Professional Java Programmer certificate
The contents are: Basics (JDK basic tools, main classes, main method, ...), variables (strings, numbers, primitives, arrays, casting, ...), objects and classes (fields, methods, instantiation, Encapsulation, ...), methods (arguments and return values, static, overwriting and overloading, ...), selected classes of the Java class library (String, StringBuilder, Dates, ArrayList, List, ...), jump commands (If / Else, Switch, Loops), inheritance (subclasses and superclasses, polymorphism, abstract classes, interfaces), lambda expressions, exception handling (exceptions, errors, catching, throwing, multicatch)
The certificate is awarded after a computer-based examination in a certification center. As part of the current certification for Java 8, 70 multiple-choice questions must be answered within 150 minutes . As with all Oracle certifications, some of the questions are not assessed without realizing which they are. Those who can correctly answer 65 percent or more percent of the questions have passed. The test result can be found after a short time under CertView from Oracle.
Oracle Certified Professional Java SE7 Programmer
The IT certificate Oracle Certified Professional Java Programmer (formerly Sun Certified Programmer for the Java Platform , including Sun Certified Java Programmer (SCJP) ) is used to detect detailed knowledge in Java - programming . It serves as a prerequisite for further certificates.
The contents are: Java class design (modifier, overwriting, overloading, instanceof, casts, virtual method calls, hashCode, equals, toString, ...), extended Java class design (abstract classes, static and final, nested classes, enumerations, ..) .), object-oriented design principles (interfaces vs. classes, cohesion and coupling, is-a, has-a, singletons, DAO, factory), generics & collections (generic classes, diamond type inference, wrapper classes, autoboxing, list , Set, Deque, Map Implementations, Comparator, Comparable, Sorting and Searching), String Processing (Searching, Parsing, Composition, Scanner, StringTokenizer, StringBuilder, String, Formatter, Regular Expressions, Format Strings, ...), Exceptions and Assertions ( throw, throws, multicatch, try-with-resources, AutoCloseable, own exceptions, invariants and assertions), Java I / O Fundamentals (console read and write, streams, files, BufferedReader & -Writer, FileReader & -Writer, DataInputStream & - O utputStream, ObjectInputStream & -OutputStream, PrintWriter, ...), NOK 2 (Path, delete, copy, move, read & change file and directory attributes, DirectoryStream, FileVisitor, PathMatcher, WatchService, ...), JDBC (Driver, Connection, Statement, ResultSet, DriverManager, Queries & Results, Iterating, Transactions, RowSet, RowSetProvider, RowSetFactory, PreparedStatements, CallableStatements, ...), Threads (Thread, Runnable, Thread-Lifecycle, Synchronization, Thread-Safe- Programming, ...), Concurrency (Locks, ReadWriteLock, ReentrantLock, Executors, ExecutorService, Callable, Future, Fork / Join Framework, ...), Localization (Locale, Resource Bundles, Formatting of Date, Number, Currencies, Language and country codes, ...)
The certificate is awarded after a computer-based examination in a certification center. As part of the current certification for Java 7, 90 exam questions must be answered within 150 minutes using multiple choice and drag and drop methods . Those who can correctly answer 65 percent or more percent of the questions have passed. The examination result will be communicated immediately after the examination.
