如何在java中将负双值转换为二进制值？

double negativeValue = -123.456;
String hexString = Double.toHexString(negativeValue);

String binaryString = new BigInteger(hexString, 16).toString(2);

public class NegativeDoubleToBinary {
    public static void main(String[] args) {
        double negativeValue = -123.456;
        String hexString = Double.toHexString(negativeValue);
        String binaryString = new BigInteger(hexString, 16).toString(2);
        System.out.println("二进制表示：" + binaryString);
    }
}
