java 文件解压（zip或rar）源代码

分享文件解压的源码作为参考：

修改文件路径即可使用下面代码，

public static void zipGetIcon() throws IOException{

		// TODO Auto-generated method stub
		ZipInputStream zis = new ZipInputStream(new FileInputStream("D:\\a.zip"));
		ZipEntry entry = null;
		ZipFile file = new ZipFile("D:\\a.zip");
		int ch = -1;
		byte[] buf = new byte[8 * 1024];
		while((entry = zis.getNextEntry()) != null){
			System.out.println(entry);
			File outFile = new File("D:\\kingfo_zhou\\" + entry.getName() + ".jpg");
			if(!outFile.getParentFile().exists()){
				outFile.getParentFile().mkdirs();
			}
			if(!outFile.exists()){
				outFile.createNewFile();
			}
			FileOutputStream out = new FileOutputStream(outFile);
			InputStream is = file.getInputStream(entry);
			while((ch = is.read(buf)) != -1){
				out.write(buf, 0, ch);
				out.flush();
			}
			out.close();
		}
		zis.close();
		file.close();
		System.out.println();
	}

可以修改这个方法，路径对外开发等，或者命名规则按照用户自定义也可以。
