    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.

    `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.
    `static Package[]` | Package.`getPackages()` | Returns all of the `Package`s defined by the caller's class loader and its ancestors.
