Java requires Keyword
Example
Use requires
in a module's module-info.java file:
module mymodule {
requires module1;
requires transitive module2;
requires static module3;
}
Definition and Usage
The requires
keyword is a module directive that specifies a different module which this module depends on.
There are two modifiers which can be added to the requires
directive: transitive
and static
The transitive
modifier allows other modules to use this module without also having to declare this same requirement.
The static
modifier makes the requirement optional during runtime. It allows this module to run even if the other module is not present.
Note: The requires
keyword is a module directive meant to be used in the module-info.java file of a module.
The requires
keyword was new in Java 9.
