I'm just copying the example from this github project page without any change and it's giving me a compile error

To reproduce, add this dependency to your pom

<dependency>
  <groupId>com.hankcs</groupId>
  <artifactId>aho-corasick-double-array-trie</artifactId>
  <version>1.2.1</version>
</dependency>

Then try to run this:

    // Collect test data set
    TreeMap<String, String> map = new TreeMap<String, String>();
    String[] keyArray = new String[]
            {
                    "hers",
                    "his",
                    "she",
                    "he"
            };
    for (String key : keyArray)
    {
        map.put(key, key);
    }
    // Build an AhoCorasickDoubleArrayTrie
    AhoCorasickDoubleArrayTrie<String> acdat = new AhoCorasickDoubleArrayTrie<String>();
    acdat.build(map);
    // Test it
    final String text = "uhers";
    acdat.parseText(text, (begin, end, value) -> {
        System.out.printf("[%d:%d]=%s\n", begin, end, value);
    });

The compile error is 

The method parseText(CharSequence, AhoCorasickDoubleArrayTrie.IHit<String>) is ambiguous for the type AhoCorasickDoubleArrayTrie<String>

Please let me know if you need anything to clarify. You should be able to reproduce this with what I have provided here though.

Also, it's been suggested this may be a duplicate question when I posted this previously, but I do not think that's the case as that question is not related to lambda functions. If I'm wrong, please help me understand how that question's answer can resolve what I'm experiencing

AhoCorasickDoubleArrayTrie有两种方法称为parseText，一种带有IHit，另一种带有IHitCancellable作为参数。两个接口都声明了一个方法boolean hit(int begin, int end, V value)，因此通过使用 lambda，编译器不知道您打算调用什么方法。

我还没有通过谷歌搜索找到一个快速的解决方案，但你可以做的是声明你自己的类扩展AhoCorasickDoubleArrayTrie了一个自己的方法，该方法在具有你想要使用的接口的超类中调用预期的方法，例如

void myParseText(String text, IHit<V> hit) {
    super.parseText(text, hit);
}
