JarOutputStream

public class JarOutputStream
extends ZipOutputStream

java.lang.Object
↳	java.io.OutputStream
	↳	java.io.FilterOutputStream
		↳	java.util.zip.DeflaterOutputStream
			↳	java.util.zip.ZipOutputStream
				↳	java.util.jar.JarOutputStream

The JarOutputStream class is used to write the contents of a JAR file to any output stream. It extends the class java.util.zip.ZipOutputStream with support for writing an optional Manifest entry. The Manifest can be used to specify meta-information about the JAR file and its entries.

`void`	`finish()` Finishes writing the contents of the ZIP output stream without closing the underlying stream.
`void`	`putNextEntry(ZipEntry e)` Begins writing a new ZIP file entry and positions the stream to the start of the entry data.
`void`	`setComment(String comment)` Sets the ZIP file comment.
`void`	`setLevel(int level)` Sets the compression level for subsequent entries which are DEFLATED.
`void`	`setMethod(int method)` Sets the default compression method for subsequent entries.
