Which of this package is used for invoking a method remotely?Optionsjava.awtjava.rmijava.utiljava.applet

The package used for invoking a method remotely in Java is java.rmi.

Here's a step-by-step explanation:

1. java.awt: This package is used for creating user interfaces and for painting graphics and images. It's not used for invoking methods remotely.

2. java.rmi: This stands for Java Remote Method Invocation. It's a Java API that performs the object-oriented equivalent of remote procedure calls (RPC), with support for direct transfer of serialized Java classes and distributed garbage collection. So, this is the correct answer.

3. java.util: This package contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes. It's not used for invoking methods remotely.

4. java.applet: This package is deprecated. It was used for creating applets, which are small programs that can be embedded in a webpage. It's not used for invoking methods remotely.
