Uses of Package in java.lang

Methods in java.lang that return Package
Modifier and Type	Method	Description
`protected Package`	ClassLoader.`definePackage(String name, String specTitle, String specVersion, String specVendor, String implTitle, String implVersion, String implVendor, URL sealBase)`	Defines a package by name in this `ClassLoader`.
`Package`	ClassLoader.`getDefinedPackage(String name)`	Returns a `Package` of the given name that has been defined by this class loader.
`Package[]`	ClassLoader.`getDefinedPackages()`	Returns all of the `Package`s that have been defined by this class loader.
`Package`	Class.`getPackage()`	Gets the package of this class.
`protected Package`	ClassLoader.`getPackage(String name)`	Deprecated. If multiple class loaders delegate to each other and define classes with the same package name, and one such loader relies on the lookup behavior of `getPackage` to return a `Package` from a parent loader, then the properties exposed by the `Package` may not be as expected in the rest of the program.
`static Package`	Package.`getPackage(String name)`	Deprecated. If multiple class loaders delegate to each other and define classes with the same package name, and one such loader relies on the lookup behavior of `getPackage` to return a `Package` from a parent loader, then the properties exposed by the `Package` may not be as expected in the rest of the program.
`protected Package[]`	ClassLoader.`getPackages()`	Returns all of the `Package`s that have been defined by this class loader and its ancestors.
