在Java中使用zlib压缩数据可以通过Java标准库中的Deflater和Inflater类来实现。以下是一个示例代码：
import java.util.zip.Deflater; import java.util.zip.Inflater; public class ZlibCompression { public static byte[] compressData(byte[] data) { Deflater deflater = new Deflater(); deflater.setInput(data); deflater.finish(); byte[] buffer = new byte[1024]; int compressedDataLength = deflater.deflate(buffer); byte[] compressedData = new byte[compressedDataLength]; System.arraycopy(buffer, 0, compressedData, 0, compressedDataLength); deflater.end(); return compressedData; } public static byte[] decompressData(byte[] compressedData) { Inflater inflater = new Inflater(); inflater.setInput(compressedData); byte[] buffer = new byte[1024]; int decompressedDataLength = inflater.inflate(buffer); byte[] decompressedData = new byte[decompressedDataLength]; System.arraycopy(buffer, 0, decompressedData, 0, decompressedDataLength); inflater.end(); return decompressedData; } public static void main(String[] args) { String input = "Hello, world!"; byte[] inputData = input.getBytes(); byte[] compressedData = compressData(inputData); byte[] decompressedData = decompressData(compressedData); String output = new String(decompressedData); System.out.println(output); } } 在上面的示例中，我们定义了compressData和decompressData方法来分别压缩和解压数据。在main方法中，我们先将字符串"Hello, world!"转换为字节数组，然后进行压缩和解压操作，最后打印解压后的字符串。
