### Question:
JavaTypes { public static boolean isPrimitiveDefault(Object o, int typeCode) { switch (typeCode) { case BOOLEAN: return ((Boolean) o).equals(Boolean.FALSE) ? true : false; case BYTE: return ((Byte) o) == 0 ? true : false; case SHORT: return ((Short) o) == 0 ? true : false; case INT: return ((Integer) o) == 0 ? true : false; case LONG: return ((Long) o) == 0L ? true : false; case FLOAT: return ((Float) o) == 0.0F ? true : false; case CHAR: return ((Character) o) == '\u0000' ? true : false; case DOUBLE: return ((Double) o) == 0.0d ? true : false; } return false; }  static int getTypeCode(Class<?> type); static Class<?> classForName(String name, ClassMetaData context); static Class<?> classForName(String name, ClassMetaData context, ClassLoader loader); static Class<?> classForName(String name, ClassMetaData context, ClassLoader loader, boolean mustExist); static Class<?> classForName(String name, ValueMetaData context); static Class<?> classForName(String name, ValueMetaData context, ClassLoader loader); static Class<?> classForName(String name, ValueMetaData context,
            ClassLoader loader, boolean mustExist); static Object convert(Object val, int typeCode); static boolean maybePC(FieldMetaData field); static boolean maybePC(ValueMetaData val); @SuppressWarnings("unchecked") static List<T> toList(Object val, Class<T> elem, boolean mutable); static Object toArray(Collection<?> coll, Class<?> elem); static boolean isPrimitiveDefault(Object o, int typeCode); static final int BOOLEAN; static final int BYTE; static final int CHAR; static final int DOUBLE; static final int FLOAT; static final int INT; static final int LONG; static final int SHORT; static final int OBJECT; static final int STRING; static final int NUMBER; static final int ARRAY; static final int COLLECTION; static final int MAP; static final int DATE; static final int PC; static final int BOOLEAN_OBJ; static final int BYTE_OBJ; static final int CHAR_OBJ; static final int DOUBLE_OBJ; static final int FLOAT_OBJ; static final int INT_OBJ; static final int LONG_OBJ; static final int SHORT_OBJ; static final int BIGDECIMAL; static final int BIGINTEGER; static final int LOCALE; static final int PC_UNTYPED; static final int CALENDAR; static final int OID; static final int INPUT_STREAM; static final int INPUT_READER; static final int ENUM; static final int LOCAL_DATE; static final int LOCAL_TIME; static final int LOCAL_DATETIME; static final int OFFSET_TIME; static final int OFFSET_DATETIME; }### Answer:
@Test public void testIsPrimitiveDefault() { assertTrue(JavaTypes.isPrimitiveDefault(_types.getBoolean(), JavaTypes.BOOLEAN)); assertTrue(JavaTypes.isPrimitiveDefault(_types.getChar(), JavaTypes.CHAR)); assertTrue(JavaTypes.isPrimitiveDefault(_types.getDouble(), JavaTypes.DOUBLE)); assertTrue(JavaTypes.isPrimitiveDefault(_types.getInt(), JavaTypes.INT)); assertTrue(JavaTypes.isPrimitiveDefault(_types.getLong(), JavaTypes.LONG)); assertTrue(JavaTypes.isPrimitiveDefault(_types.getShort(), JavaTypes.SHORT)); }
