I have the following Java code that uses a local class.



import java.util.Arrays;

public class X<T>
void m()
class Z

for (Object o : Arrays.asList(1, 2, 3))
if (o instanceof Z)




It does not compile with the following error message:



X.java:8: error: illegal generic type for instanceof
if (o instanceof Z)
^
1 error


I understand that the local class Z inherits the generic type signature of X<T>, being an inner class. The same kind of compilation error appears in this example, where Z is not local, but still inner:



import java.util.Arrays;

public class X<T>
class Z

void m()
for (Object o : Arrays.asList(1, 2, 3))
if (o instanceof Z) // Compilation error




It can be worked around either by making Z non-inner / static:



import java.util.Arrays;

public class X<T>
static class Z

void m()
for (Object o : Arrays.asList(1, 2, 3))
if (o instanceof Z) // Compiles now




Or by qualifying X.Z:



import java.util.Arrays;

public class X<T>
class Z

void m()
for (Object o : Arrays.asList(1, 2, 3))
if (o instanceof X.Z) // Compiles now
if (o instanceof X<?>.Z) // Also





But how can I qualify a local class, or work around this limitation, without changing the local class itself?

To me this seems to be an oversight or limitation in the Java language and I do not think it is possible.



The referenced type in an instanceof expression must be reifiable according to JLS 4.7, meaning that it must be expressed as a reifiable type by its fully qualified name. At the same time, JLS 6.7 states that local classes do not have a fully qualified name, they can therefore not be expressed as reifiable.



If you declare Z as generic, the instanceof operator treats Z as a raw type where all generic properties to it - in this case the enclosing class - are considered raw as well. (Similar to a generic methods of a raw type being considered as raw despite any generic signature. This is a measure to retain backwards compatiblity of type generification.) Since any raw type is reifiable, declaring Z to be generic will compile.

A possible workaround is to use reflection:



import java.util.Arrays;

public class X<T>
void m()
class Z

for (Object o : Arrays.asList(1, 2, 3))
if (Z.class.isInstance(o))

    Apparently, by making Z generic compilation succeeds. I expected that to require <T> as the type parameter, but you just have to make it generic, so anything will do



    import java.util.Arrays;

    public class X<T>
    void m()
    class Z<Anything>

    for (Object o : Arrays.asList(1, 2, 3))
    if (Z.class.isInstance(o))




    Proper solution would be qualify the local class, but I don't think you can. Either you refactor it to a private static class or that's probably the best you can get.

    This should work either. Using reflection too. But seems a valid solution.



    import java.util.Arrays;

    public class X<T>


    void m()

    class Z2


    for(Object o: Arrays.asList(1,2,3))
    if(Z2.class.isAssignableFrom(o.getClass()))

    A possible workaround is to use reflection:



    import java.util.Arrays;

    public class X<T>
    void m()
    class Z

    for (Object o : Arrays.asList(1, 2, 3))
    if (Z.class.isInstance(o))

            Apparently, by making Z generic compilation succeeds. I expected that to require <T> as the type parameter, but you just have to make it generic, so anything will do



            import java.util.Arrays;

            public class X<T>
            void m()
            class Z<Anything>

            for (Object o : Arrays.asList(1, 2, 3))
            if (Z.class.isInstance(o))




            Proper solution would be qualify the local class, but I don't think you can. Either you refactor it to a private static class or that's probably the best you can get.

              Once you make Z generic, you don't need to apply the reflection workaround anymore...

            This should work either. Using reflection too. But seems a valid solution.



            import java.util.Arrays;

            public class X<T>


            void m()

            class Z2


            for(Object o: Arrays.asList(1,2,3))
            if(Z2.class.isAssignableFrom(o.getClass()))

            • I didn't downvote, but I guess it's because there's a slightly better way to use reflection here, as I've mentioned in my own answer
