jdk1.8에서 zip 압축파일 해제하는 코드

Java JDK 1.8에서 ZIP 압축 파일을 해제하는데는 `java.util.zip` 패키지를 사용할 수 있습니다. 다음은 Java 코드 예제로, ZIP 파일을 해제하는 간단한 방법을 보여줍니다.

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;

public class UnzipFile {

    public static void main(String[] args) {
        String zipFilePath = "path_to_your_zip_file.zip";
        String destDirectory = "path_to_destination_directory";

        try {
            unzip(zipFilePath, destDirectory);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void unzip(String zipFilePath, String destDirectory) throws IOException {
        File destDir = new File(destDirectory);
        if (!destDir.exists()) {
            destDir.mkdir();
        }

        try (ZipInputStream zipIn = new ZipInputStream(new FileInputStream(zipFilePath))) {
            ZipEntry entry = zipIn.getNextEntry();

            while (entry != null) {
                String filePath = destDirectory + File.separator + entry.getName();
                if (!entry.isDirectory()) {
                    extractFile(zipIn, filePath);
                } else {
                    File dir = new File(filePath);
                    dir.mkdir();
                }
                zipIn.closeEntry();
                entry = zipIn.getNextEntry();
            }
        }
    }

    private static void extractFile(ZipInputStream zipIn, String filePath) throws IOException {
        try (BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(filePath))) {
            byte[] bytesIn = new byte[4096];
            int read = 0;
            while ((read = zipIn.read(bytesIn)) != -1) {
                bos.write(bytesIn, 0, read);
            }
        }
    }
}

위 코드에서 `zipFilePath` 변수에 압축 해제하려는 ZIP 파일의 경로를 설정하고, `destDirectory` 변수에 압축을 해제하여 파일을 저장할 디렉토리의 경로를 설정합니다.

이 코드는 ZIP 파일을 읽고, 각 항목(파일 또는 디렉토리)을 압축 해제하여 지정된 디렉토리에 저장합니다.
