用Java程序实现解压缩文件
package com.huawei.globe;
import java.util.zip.*;
import java.io.*;
public class Compress {
public Compress() {
}
// 压缩目录下的文件
public void compress(String zipFileName, String inputFile) throws Exception {
compress(zipFileName, new File(inputFile));
}
// 压缩文件
public void compress(String zipFileName, File inputFile) throws Exception {
ZipOutputStream out = new ZipOutputStream(new FileOutputStream(
zipFileName));
compress(out, inputFile, "");
System.out.println("压缩成功!");
out.close();
}
public void compress(ZipOutputStream out, File f, String base)
throws Exception {
System.out.println("正在压缩 " + f.getName());
if (f.isDirectory()) {
File[] fl = f.listFiles();
out.putNextEntry(new ZipEntry(base + "/"));
base = base.length() == 0 ? "" : base + "/";
for (int i = 0; i < fl.length; i++) {
compress(out, fl[i], base + fl[i].getName());
}
} else {
out.putNextEntry(new ZipEntry(base));
FileInputStream in = new FileInputStream(f);
int b;
while ((b = in.read()) != -1)
out.write(b);
in.close();
}
}
// 解压缩文件
public void upCompress(String zipFileName, String outputDirectory)
throws Exception {
ZipInputStream in = new ZipInputStream(new FileInputStream(zipFileName));
ZipEntry z;
while ((z = in.getNextEntry()) != null) {
System.out.println("正在解压 " + z.getName());
if (z.isDirectory()) {
String name = z.getName();
name = name.subs

this.size=size;
