For unordered access as defined in the java.util.Map interface, the java.util.concurrent.ConcurrentHashMap implements java.util.concurrent.ConcurrentMap. [2] The mechanism is a hash access to a hash table with lists of entries, each entry holding a key, a value, the hash, and a next reference.
List comprehension is a syntactic construct available in some programming languages for creating a list based on existing lists. It follows the form of the mathematical set-builder notation (set comprehension) as distinct from the use of map and filter functions.
The Java Class Library is the standard library, developed to support application development in Java. It is controlled by Oracle in cooperation with others through the Java Community Process program. [72] Companies or individuals participating in this process can influence the design and development of the APIs.
Note how the use of A[i][j] with multi-step indexing as in C, as opposed to a neutral notation like A(i,j) as in Fortran, almost inevitably implies row-major order for syntactic reasons, so to speak, because it can be rewritten as (A[i])[j], and the A[i] row part can even be assigned to an intermediate variable that is then indexed in a separate expression.
JShell is a Java read-eval-print loop which was first introduced in the JDK 9. [1] It is tracked by JEP 222 jshell: The Java Shell (Read-Eval-Print Loop). [2] One reason why JShell was proposed for Java 9 is the lack of a standard interactive environment for the language; the de facto library to use a Java REPL was often BeanShell, which has been dormant since 2003, and arbitrarily diverged ...
Oracle WebLogic Server forms part of Oracle Fusion Middleware portfolio and supports Oracle, IBM Db2, Microsoft SQL Server, MySQL Enterprise and other JDBC-compliant databases. Oracle WebLogic Platform also includes: Formerly, JRockit, a custom JVM (discontinued with some components merged into HotSpot/OpenJDK following Sun acquisition) [26]
Several libraries are based on top of OCI, including: Oracle's Type-II JDBC Driver (part-Java, part native) Oracle's enhanced C++ library, Oracle C++ Call Interface (OCCI), which provides an object-oriented interface with the object-relational features of the Oracle database. Oracle's OLE DB Driver; Oracle's ODBC Driver; Oracle's .NET Data ...
The Java NIO APIs are provided in the java.nio package and its subpackages. The documentation by Oracle identifies these features. Buffers for data of primitive types; Character set encoders and decoders; A pattern-matching facility based on Perl-style regular expressions (in package java.util.regex) Channels, a new primitive I/O abstraction
