Given:andWhat is the result?

Examice · Accepted Answer

The compilation fails because the setValue method in the MyType class requires the type to be specified. The line 'type.setValue(1234)' tries to set an integer value to 'type', which is of type 'MyType<?>', leading to a compilation error since the compiler cannot ensure that the type parameter matches the given value type.

The method setValue(capture#1-of ?) in the type MyType<capture#1-of ?> is not applicable for the arguments (int)
