### Question:
FieldUtils { public static String genSetMethodName(Field field) { int len = field.getName().length(); StringBuilder sb = new StringBuilder(len + 3); sb.append("set").append(field.getName()); if (Character.isLowerCase(sb.charAt(PREFIX_SET_METHOD_INDEX))) { sb.setCharAt(PREFIX_SET_METHOD_INDEX, Character.toUpperCase(sb.charAt(PREFIX_SET_METHOD_INDEX))); } return sb.toString(); }  static void writeField(final Object target, final Field field, final Object value); static void writeField(final Object target, final String fieldName, final Object value); static Object readField(final Object target, final Field field); static Field getField(final Class<?> klass, String fieldName); static List<Field> getAllField(final Class<?> klass); static String genGetMethodName(Field field); static String genSetMethodName(Field field); static Field[] scanAllField(final Class<?> klass, List<Class<? extends Annotation>> annotations); static void injectionStaticField(Map<String, T> templates, Class<?> target, Function<T, String> fun);  }### Answer:
@Test public void testGenSetMethodName() { assertTrue("setTest1".equals(FieldUtils.genSetMethodName(FieldUtils.getField(FieldUtilsTest.class, "test1")))); }
