### Question:
Strings { public static boolean startsWith(String text, String prefix) { return Strings.startsWith(text, prefix, true); } private  Strings(); static String substitute(String string, Map<String, ? extends Object> replace); static String substitute(String string, Map<String, ? extends Object> replace, Locale locale); static String findPlaceHolder(String string); static String clearEscapedPlaceHolder(String dirty); static T proper(T returnIfNotEmpty, T alternative); static String toCamel(String snake); static String toSnake(String camel); static String join(T... joinees); static String joinBy(String separator, T... joinees); static String join(List<T> joinees); static String joinBy(String separator, List<T> joinees); static boolean isBlank(CharSequence suspect); static boolean containBlank(CharSequence suspect); static String removeBlanks(CharSequence target); static boolean isEmpty(CharSequence suspect); static boolean isEmpty(CharSequence suspect, boolean removeBlanks); static String reverse(String reversee); static String trim(String target); static String[] split(String regex, String target); static boolean equalsIgnoreCase(String source, String destination); static boolean startsWith(String text, String prefix); static boolean startsWith(String text, String prefix, boolean textCompare); static boolean endsWith(String text, String prefix); static boolean endsWith(String text, String prefix, boolean textCompare); static String escapeHTML(CharSequence html); static String escapeRegex(CharSequence text);  }### Answer:
@Test public void startsWithテスト() { assertThat(Strings.startsWith("", ""), is(false)); assertThat(Strings.startsWith("", null), is(false)); assertThat(Strings.startsWith(null, null), is(false)); assertThat(Strings.startsWith(null, ""), is(false)); assertThat(Strings.startsWith("/start/hoge", "/start"), is(true)); assertThat(Strings.startsWith("/Start/hoge", "/start"), is(true)); assertThat(Strings.startsWith("/Start/hoge", "/start", false), is(false)); }
