在Java中，可以使用java.util.zip包中的Deflater和Inflater类来进行字符串的压缩和解压缩操作。以下是一个简单的示例代码：
import java.util.zip.Deflater; import java.util.zip.Inflater; public class Main { public static byte[] compressString(String input) { try { byte[] inputBytes = input.getBytes(); Deflater deflater = new Deflater(); deflater.setInput(inputBytes); deflater.finish(); byte[] outputBytes = new byte[inputBytes.length]; int compressedSize = deflater.deflate(outputBytes); byte[] compressedBytes = new byte[compressedSize]; System.arraycopy(outputBytes, 0, compressedBytes, 0, compressedSize); return compressedBytes; } catch (Exception e) { e.printStackTrace(); return null; } } public static String decompressString(byte[] input) { try { Inflater inflater = new Inflater(); inflater.setInput(input); byte[] outputBytes = new byte[input.length]; int decompressedSize = inflater.inflate(outputBytes); byte[] decompressedBytes = new byte[decompressedSize]; System.arraycopy(outputBytes, 0, decompressedBytes, 0, decompressedSize); return new String(decompressedBytes); } catch (Exception e) { e.printStackTrace(); return null; } } public static void main(String[] args) { String input = "Hello, this is a test string for compression."; byte[] compressedData = compressString(input); String decompressedData = decompressString(compressedData); System.out.println("Original data: " + input); System.out.println("Compressed data: " + new String(compressedData)); System.out.println("Decompressed data: " + decompressedData); } } 在上面的示例中，compressString方法用于压缩输入的字符串，而decompressString方法用于解压缩输入的字节数组。通过这两个方法，可以实现字符串的压缩和解压缩操作。
