How does Java resolve a name clash between two imported packages?

It automatically selects one
It throws a runtime exception
The programmer must specify which class to use
It merges the two classes

The correct answer is: The programmer must specify which class to use

Name clash occurs when there are two classes with the same name in two different packages. When this happens, Java allows us to import both packages and use the classes within them. However, if we try to use a method or variable within the class without specifying which class it belongs to, Java will not know which class to use and this results in a compilation error. So, in order to resolve this ambiguity, the programmer has to explicitly specify which class they want to use in their code. This can be done by specifying the package name followed by the class name, separated by a dot. For example, "package1.ClassA" or "package2.ClassA". Therefore, option C is the correct answer. Options A, B, and D are incorrect as Java does not have any default behavior for resolving name clashes and will always require the programmer to specify the class to use.
