A Java gist on zip and unzip

Compressing is one of the major actions that can be issued in our code when it comes to writing files. Thus I find a simple java snippet on zip and unzip essential and has to be easily accessed.

This gist is in plain java and stores two files in a zip. Once done the produced zip is open and its contents are evaluated.

	import org.apache.commons.io.IOUtils;
	import org.junit.Assert;
	import org.junit.Test;

	import java.io.*;
	import java.nio.file.Files;
	import java.util.zip.ZipEntry;
	import java.util.zip.ZipInputStream;
	import java.util.zip.ZipOutputStream;

	private static final String TEXT_ENTRY_1 = "text1.txt";
	private static final String TEXT_ENTRY_2 = "text2.txt";

	@Test
	public void zipAndUnzip() throws IOException {

	String text1 = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do ";
	String text2 = "eiusmod tempor incididunt ut labore et dolore magna aliqua. ";

	File tempZip = File.createTempFile("temp",".zip");

	try(OutputStream outputStream = new FileOutputStream(tempZip);
	ZipOutputStream zipOutputStream = new ZipOutputStream(outputStream)) {

	zipOutputStream.putNextEntry(new ZipEntry(TEXT_ENTRY_1));
	zipOutputStream.write(text1.getBytes());
	zipOutputStream.closeEntry();

	zipOutputStream.putNextEntry(new ZipEntry(TEXT_ENTRY_2));
	zipOutputStream.write(text2.getBytes());
	zipOutputStream.closeEntry();
	}

	try(InputStream inputStream = new FileInputStream(tempZip);
	ZipInputStream zipInputStream = new ZipInputStream(inputStream)) {

	ZipEntry entry = null;

	while ((entry=zipInputStream.getNextEntry())!=null) {
	if(entry.getName().equals(TEXT_ENTRY_1)) {
	Assert.assertEquals(text1, IOUtils.toString(zipInputStream));
	}
	if(entry.getName().equals(TEXT_ENTRY_2)) {
	Assert.assertEquals(text2,IOUtils.toString(zipInputStream));
	}
	zipInputStream.closeEntry();
	}
	} finally {
	Files.deleteIfExists(tempZip.toPath());
	}
	}
