java如何打包zip等压缩文件
? 直接调用jdk的类可以了。
?package javaio;
import java.io.*;
import java.util.zip.*;
public class ZipCompress{
?public static void main(String args[]){
??try{
???ZipCompress zip=new ZipCompress();
???FileOutputStream fileOut=new FileOutputStream("Example.zip");
???CheckedOutputStream checkOut=new CheckedOutputStream(fileOut,new CRC32());
???ZipOutputStream zipOut=new ZipOutputStream(new BufferedOutputStream(checkOut));
???zipOut.setComment("This is a java zipping test file");
???//String fileName=zip.getClass().getResource("test.txt").toString();
???String fileName="E:\\test.txt";
???System.out.println(fileName);
???System.out.println(zip.getClass());
???BufferedReader in=new BufferedReader(new FileReader(fileName));
???zipOut.putNextEntry(new ZipEntry(fileName));//建立压缩实体
???int ch;
???//当压缩过程未结束时继续读写
???while((ch=in.read())!=-1){
????zipOut.write(ch);
????System.out.println(ch);
???}
???in.close();
???zipOut.close();
??}catch(IOException e){
???System.out.println(e.toString());
??}
?}
}
