Java 有没有办法从文本文件中读取J48修剪过的树？

给定包含以下内容的文本文件（例如weather.txt）：

我当前的代码（如下）正在打印上面的树：

    J48 cls = new J48();
    Instances inst = new Instances(new BufferedReader(new FileReader("data.txt")));
    inst.setClassIndex(inst.numAttributes() - 1);
    cls.buildClassifier(inst);

    weka.core.SerializationHelper.write("j48.model", cls);

    J48 cls2 = (J48) weka.core.SerializationHelper.read("j48.model");
    System.out.println(cls2);

---

我的目标是将这些树保存在文本文件中。然后把它们读回来。如何在java中读取它们？

为什么不将J48的toString写入一个文件，然后读取它？是的。因此，基本上我已经为同样的问题构建了一个手动解析器。但我相信应该有一些图书馆来做这件事。

@relation weather

@attribute outlook {sunny, overcast, rainy}
@attribute temperature numeric
@attribute humidity numeric
@attribute windy {TRUE, FALSE}
@attribute play {yes, no}

@data

    J48 cls = new J48();
    Instances inst = new Instances(new BufferedReader(new FileReader("data.txt")));
    inst.setClassIndex(inst.numAttributes() - 1);
    cls.buildClassifier(inst);

    weka.core.SerializationHelper.write("j48.model", cls);

    J48 cls2 = (J48) weka.core.SerializationHelper.read("j48.model");
    System.out.println(cls2);
