实现代码如下：（在当前包文件夹下新建一个文本文件：123.txt，将其压缩到test.zip）
import java.io.BufferedOutputStream;
import java.io.BufferedReader;
import java.io.FileOutputStream;
import java.io.FileReader;
import java.util.zip.Adler32;
import java.util.zip.CheckedOutputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;
public class Zipstream {
public static void main(String[] args) throws Exception{
FileOutputStream f=new FileOutputStream("text.zip");
CheckedOutputStream csum=new CheckedOutputStream(f,new Adler32());
ZipOutputStream zos=new ZipOutputStream(csum);
BufferedOutputStream out = new BufferedOutputStream(zos);
zos.setComment("A test of Java Ziping!");
BufferedReader in =new BufferedReader(new FileReader("123.txt"));
zos.putNextEntry(new ZipEntry("123.txt"));
int c;
while((c = in.read()) != -1){
out.write(c);
}
in.close();
out.flush();
out.close();
}
}
