The JPype java.* type definitions. They cover imports like from java.util import ArrayList.
There are two mutually exclusive variants distributed under different names:
java-stubs (no automated Java string to Python string conversions)
java-stubs-converted-strings (with the conversions)
Some details from JPype string conversions documentation:
The convertStrings argument controls whether Java strings are automatically converted to Python strings. By default, this behavior is disabled (convertStrings=False) to preserve Java string methods and avoid unnecessary conversions.
If enabled (convertStrings=True), Java strings are returned as Python strings, but this can impact performance and chaining of Java string methods. This option is consisted a legacy option as it will result in unncessary calls to str() every time a String is passed from Java.
Best practice: Set convertStrings=False unless your application explicitly requires automatic conversion.
Which version you need depends on the convertStrings value used when starting the JVM.
Both of these distributions provide the java-stubs package providing type definitions for the whole java.* namespace.
The stubs are produced with CERN’s stubgenj.
There’s a related JPype discussion.
Known limitations
The types are tied to a specific Java version (currently OpenJDK 25).
The JPype version used when generating the types may affect them, currently only one version is used.
A few Java -> Python stubgenj translation problems have been reported, some are very difficult to resolve in a way that will satisfy all users (more: https://gitlab.cern.ch/scripting-tools/stubgenj/-/issues).
Internal documentation
Run ./generate to regenerate the stubs.
