本文整理了Java中java.lang.Float.hashCode()方法的一些代码示例，展示了Float.hashCode()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。Float.hashCode()方法的具体详情如下：
包路径：java.lang.Float
类名称：Float
方法名：hashCode

Float.hashCode介绍

[英]Returns a hash code for this Float object. The result is the integer bit representation, exactly as produced by the method #floatToIntBits(float), of the primitive float value represented by this Floatobject.
[中]返回此浮点对象的哈希代码。结果是该Floatobject表示的基本浮点值的整数位表示，与#floatToIntBits（float）方法产生的结果完全相同。

代码示例

/**
 * Returns a hash code for {@code value}; equal to the result of invoking {@code ((Float)
 * value).hashCode()}.
 *
 * <p><b>Java 8 users:</b> use {@link Float#hashCode(float)} instead.
 *
 * @param value a primitive {@code float} value
 * @return a hash code for the value
 */
public static int hashCode(float value) {
 // TODO(kevinb): is there a better way, that's still gwt-safe?
 return ((Float) value).hashCode();
}
