Java如何使用ZipFile解压缩zip文件？
在此示例中，我们使用java.util.zip.ZipFile该类解压缩并提取一个zip文件。
package org.nhooo.example.zip;
import java.util.zip.ZipFile;
import java.util.zip.ZipEntry;
import java.util.Enumeration;
import java.io.*;
public class ZipFileUnzipDemo {
public static void main(String[] args) throws Exception {
String zipName = "data.zip";
ZipFile zip = new ZipFile(zipName);
Enumeration enumeration = zip.entries();
while (enumeration.hasMoreElements()) {
ZipEntry zipEntry = (ZipEntry) enumeration.nextElement();
System.out.println("Unzipping: " + zipEntry.getName());
int size;
byte[] buffer = new byte[2048];
try (BufferedInputStream bis =
new BufferedInputStream(zip.getInputStream(zipEntry));
FileOutputStream fos =
new FileOutputStream(zipEntry.getName());
BufferedOutputStream bos =
new BufferedOutputStream(fos, buffer.length)) {
while ((size = bis.read(buffer, 0, buffer.length)) != -1) {
bos.write(buffer, 0, size);
}
bos.flush();
}
}
}
}
