在Java中实现writeBit方法

import java.io.OutputStream;

public class BitWriter {
    private OutputStream outputStream;
    private int currentByte;
    private int numBitsRemaining;

    public BitWriter(OutputStream outputStream) {
        this.outputStream = outputStream;
        this.currentByte = 0;
        this.numBitsRemaining = 8;
    }

    public void writeBit(int bit) {
        // 将bit写入到当前字节的最低位
        currentByte |= (bit & 1) << (numBitsRemaining - 1);
        numBitsRemaining--;

        if (numBitsRemaining == 0) {
            // 当前字节已满，写入到输出流并重置状态
            try {
                outputStream.write(currentByte);
                currentByte = 0;
                numBitsRemaining = 8;
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

    public void close() {
        // 如果当前字节还有剩余位，则写入到输出流
        if (numBitsRemaining < 8) {
            try {
                outputStream.write(currentByte);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        // 关闭输出流
        try {
            outputStream.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
