Question

我不明白，当我的程序读取我的yml文件时，它会读取float的类型，但它返回零或0.0。我的浮动TRIG_EDGE_LEV返回0.0但它返回1.5。

public class Loadyml {

  //static OscilloDSO1072B dso1072B = new OscilloDSO1072B("visa://192.168.53.67/USB0::0x0957::0x0588::CN55040484::INSTR") ;

  }
}

我该如何解决？

要解决您的问题 - 请使用RuntimeError: wrapped C/C++ object of type QLabel has been deleted代替double - 在Jyaml代码库中的某处，它会尝试将浮点数与 getter / setter方法（非字段）匹配反复键入float。由于您的字段属于double类型，因此基于反射的匹配失败，您将获得默认值0.0f

旁注：

使用字段和方法的盒装/对象版本，即 - float代替Double。对于存在性检查，null比0.0更有意义。（我也推荐java 8的double）。
Jyaml超级老，其代码库看起来很可怕，请考虑使用更新的yaml解析替代方法，最好使用Jackson之类的注释。
使用Jackson - 使用注释按原样映射yaml文件中的名称，并根据java约定保留代码（字段和方法应该是驼峰式的）

java：返回null或0.0
