### Question:
ClassNameUtils { public static String getComponentType(String className) { return className.replaceFirst("\\[\\]?", ""); }  static String binaryToInternal(String binaryName); static String getComponentBase(String className); static String getComponentType(String className); static int getDimensionCount(String className); static String getPackageName(String className); static @Nullable String getPrimitive(String className); static Class<?> getPrimitiveClass(String className); static @Nullable String getWrapper(String className); static String internalToBinary(String internalName); static String internalToSource(String internalName); static boolean isObject(String type); static boolean isPrimitive(String className); static boolean isPrimitiveOrWrapper(String className); static boolean isWrapper(String className); static String sourceToBinary(String sourceName); static String sourceToInternal(String sourceName); static String toFormat(String className, TypeFormat format); static String toInternal(Class<?> klazz); static List<String> toInternal(Class<?>... classes); static ReferenceType guessReferenceType(@Nonnull String s);  }### Answer:
@Test public void canGetComponentType() { String componentType; componentType = ClassNameUtils.getComponentType("[[[[[[Lsome/class;"); assertEquals("[[[[[Lsome/class;", componentType); componentType = ClassNameUtils.getComponentType("[[[Lsome.class;"); assertEquals("[[Lsome.class;", componentType); componentType = ClassNameUtils.getComponentType("some.class[][][]"); assertEquals("some.class[][]", componentType); }
