本文整理了Java中java.lang.Double.byteValue()方法的一些代码示例，展示了Double.byteValue()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Double.byteValue()方法的具体详情如下：
包路径：java.lang.Double
类名称：Double
方法名：byteValue

Double.byteValue介绍

[英]Returns the value of this Double as a byte (by casting to a byte).
[中]以字节形式返回此Double的值（通过强制转换为字节）。

代码示例

代码示例来源：origin: jfinal/jfinal

public Byte toByte(Double self) {
    return self.byteValue();
  }
}

代码示例来源：origin: hibernate/hibernate-orm

return (X) Byte.valueOf( value.byteValue() );

代码示例来源：origin: mapsforge/mapsforge

/**
 * @param value string represented numerical value
 * @return value as Byte
 */
public static Byte getByteValue(String value) {
  nBytes++;
  return parseDoubleUnit(value).byteValue();
}
