What is the difference between guava Splitter and the split method of Java's built-in string.

Java built-in ignores empty content, guava splitter is not ignored. Or you can freely choose to ignore.

/** * {@code Splitter}和{@code Joiner} 这两个对于map的相反的操作，在web框架例如spring mvc中用到过． *  * 对于get　url后面的参数和pos　form中前端参数的连接和后端的拆分都有用到．每个框架的处理思维是一样的． *  * @author doctor * * @since 2015年3月14日 下午9:00:17 */．．．．．．．．．．．．．．　　@Test    public void test_string_split() {        String[] split = "a,b,,".split(","); // java内置的会忽略空内容        assertThat(split, equalTo(Lists.newArrayList("a", "b").toArray()));    }    @Test    public void test_guava_Splitter() {        List<String> splitToList = Splitter.on(",").splitToList("a,b,,");//guava不会忽略        assertThat(splitToList, equalTo(Lists.newArrayList("a", "b", "", "")));    }　@Test    public void test_guava_Splitter_omitEmptyStrings() {        // 或者可以自由选择的忽略　，像java一样，忽略空字符串        List<String> splitToList = Splitter.on(",").omitEmptyStrings().trimResults().splitToList("a,b,,");        assertThat(splitToList, equalTo(Lists.newArrayList("a", "b")));    }
