Java arrays are structures.  You can see the definition in
gcc/libjava/gcj/array.h.  I've appended the relevant bits for your
perusal.

Most instantiations of JArray are actually created at runtime.  Only
primitive arrays are created statically.

    class __JArray : public java::lang::Object
    {
    protected:
      // This is just a hack to work around a warning emitted by the C++
      // compiler.  We initialize `length' evilly, but it doesn't know
      // that.
      __JArray () : length (0)
      {
      }
    public:
      const jsize length;
      friend jsize JvGetArrayLength (__JArray*);
    };

    template<class T>
    class JArray : public __JArray
    {
      T data[0];
    public:
      friend T* elements<>(JArray<T>& x);
      friend T* elements<>(JArray<T>* x);
      // T* getData() { return data; }
      // T& operator[](jint i) { return data[i]; }
    };
