Java Java.util.zip.ZipOutputStream用法及代码示例

//Java program demonstrating ZipOutputStream methods 
  
import java.io.FileInputStream; 
import java.io.FileOutputStream; 
import java.io.IOException; 
import java.util.Arrays; 
import java.util.zip.ZipEntry; 
import java.util.zip.ZipInputStream; 
import java.util.zip.ZipOutputStream; 
  
class ZipOutputStreamDemo 
{ 
    public static void main(String[] args) throws IOException  
    { 
          
        FileOutputStream fos = new FileOutputStream("zipfile"); 
        ZipOutputStream zos = new ZipOutputStream(fos); 
  
        //illustrating setMethod() 
        zos.setMethod(8); 
          
        //illustrating setLevel method 
        zos.setLevel(5); 
  
        ZipEntry ze1 = new ZipEntry("ZipEntry1"); 
      
        //illustrating putNextEntry method 
        zos.putNextEntry(ze1); 
      
        //illustrating setComment 
        zos.setComment("This is my first comment"); 
  
        //illustrating write() 
        for(int i = 0; i < 10; i++) 
            zos.write(i); 
      
        //illustrating write(byte b[], int off, int len) 
        byte b[] = { 11, 12, 13}; 
        zos.write(b); 
  
  
        //illustrating closeEntry() 
        zos.closeEntry(); 
          
        //Finishes writing the contents of the ZIP output stream 
        // without closing the underlying stream 
        zos.finish(); 
          
        //closing the stream 
        zos.close();

        //Reads the next ZIP file entry 
        ZipEntry ze = zin.getNextEntry(); 
  
        //the name of the entry. 
        System.out.println(ze.getName()); 
  
        //illustrating getMethod 
        System.out.println(ze.getMethod()); 
  
        //Reads up to byte.length bytes of data from this input stream 
        // into an array of bytes. 
        byte c[] = new byte[13];

        zin.closeEntry();
