Java Database Connectivity (JDBC) is an application programming interface (API) for the Java programming language which defines how a client may access a database. It is a Java-based data access technology used for Java database connectivity. It is part of the Java Standard Edition platform, from Oracle Corporation.
The Jakarta Persistence Query Language (JPQL; formerly Java Persistence Query Language) is a platform-independent object-oriented query language [1]: 284, §12 defined as part of the Jakarta Persistence (JPA; formerly Java Persistence API) specification. JPQL is used to make queries against entities stored in a relational database.
In the above example, the application might supply the values "bike" for the first parameter and "10900" for the second parameter, and then later the values "shoes" and "7400". The alternative to a prepared statement is calling SQL directly from the application source code in a way that combines code and data.
This template can take any number of unnamed parameters as parameters accompanying the template link (or name); see Examples below. Examples Use the displayed value in the code column, not the underlying source code.
All parameters are separated with the pipe character "|". The first "parameter" is always the name of the template that you wish to use and as such is not formally a parameter at all. In this case, it is Querylink. The first formal parameter passed to the template should be the name of the internal page that you wish to link.
The "autovalue" entry lets you tell VisualEditor and other tools to pre-fill this parameter with a standard value (in wikitext); this text will show up in the parameter box when users edit, and will be added to the template invocation when saved. This may be useful for cleanup templates to automatically set the date the user adds a template.
In object-oriented programming, the template method is one of the behavioral design patterns identified by Gamma et al. [1] in the book Design Patterns.The template method is a method in a superclass, usually an abstract superclass, and defines the skeleton of an operation in terms of a number of high-level steps.
Primitive wrapper classes are not the same thing as primitive types. Whereas variables, for example, can be declared in Java as data types double, short, int, etc., the primitive wrapper classes create instantiated objects and methods that inherit but hide the primitive data types, not like variables that are assigned the data type values.
