The code for creating zip files in java is as follows:
import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.util.zip.ZipEntry;import java.util.zip.ZipInputStream;import java.util.zip.ZipOutputStream;public class ZipDemo { public static void main(String[] args) throws IOException { File file = new File("test.zip"); if(!file.exists()) file.createNewFile(); String string="test ZIP!"; byte[] buffer =string.getBytes(); FileOutputStream fOutputStream = new FileOutputStream(file); ZipOutputStream zoutput = new ZipOutputStream(fOutputStream); ZipEntry zEntry = new ZipEntry("test.txt"); zoutput.putNextEntry(zEntry); zoutput.write(buffer); zoutput.closeEntry(); zoutput.close(); }}Supplementary: Let’s take a look at creating a ZIP file in JAVA, and write and read entries and data into the ZIP file.
package File; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.util.zip.ZipEntry; import java.util.zip.ZipInputStream; import java.util.zip.ZipOutputStream; public class ZipDemo {public static void main(String[] args) throws IOException {// TODO Auto-generated method stub File file = new File("test.zip"); if(!file.exists()) file.createNewFile(); String string="my name is ysd!"; byte[] buffer =string.getBytes(); byte[] BufferInput =new byte[4096]; FileOutputStream fOutputStream = new FileOutputStream(file); ZipOutputStream zoutput = new ZipOutputStream(fOutputStream); ZipEntry zEntry = new ZipEntry("one.txt"); zoutput.putNextEntry(zEntry); zoutput.write(buffer); zoutput.closeEntry(); zoutput.close(); ZipInputStream zInputStream = new ZipInputStream(new FileInputStream(file)); ZipEntry zipEntry = null; while((zipEntry=zInputStream.getNextEntry()) != null) { System.out.println(zipEntry.getName()); zInputStream.read(BufferInput); System.out.println(new String(BufferInput)); zInputStream.closeEntry(); } zInputStream.close();} }Summarize
