“Codes like a class, works like an int!”

This is a sketch of proposed enhancements to the Java Virtual Machine instruction set, and secondarily to the Java Language, to support small immutable, identityless value types. (They may also be considered as identityless aggregates, user-defined primitives, immutable records, or restricted classes.) This is an early draft, intended to describe the overall approach. Readers are expected to be familiar with the JVM bytecode instruction set.
Background

The Java VM type system offers two ways to create aggregate data types: heterogeneous aggregates with identity (classes), and homogeneous aggregates with identity (arrays). The only types that do not have identity are the eight hardwired primitive types: byte, short, int, long, float, double, char, and boolean. Object identity has footprint and performance costs, which is a major reason Java, unlike other many object oriented languag

Notice the inclusion of both Design & Development as Android App creation includes heavy focus on User Interface design
with all possible kinds of objects like buttons, imageviews, layouts, etc; unless the Android project is focused on
designing a service based component only, like web proxy, background sound calibration, background data collection and
uploading (having no User Interface).

Prerequisites:
- Basic Java knowledge: http://www.particle.kth.se/~lindsey/JavaCourse/Book/Part1/Java/Chapter01/features.html
- Basic XML, drag and drop UI Building
- Comfort of using IDEs: Eclipse(Google ADT for Android) or IntelliJ IDEA(Android Studio for Android)
- Basic SQL Database knowledge: Vogella is a great resource http://www.vogella.com/tutorials/AndroidSQLite/article.html

Tar, (short for tape archiver), is a versital tool that can be used for archiving files to disk or any other device as easily as tape. In fact, if you don't work in a data center, you will probably never use tar with a tape drive.

Often, Unix/BSD/Linux files and source code are distributed in a zipped tar file, sometimes called a tarball. Extensions for tarballs are usually .tgz or .tar.gz (gz because it was compressed using gzip, the free GNU zip program). Rarely, you may run across a tar file that is not compressed and has an extension of simply .tar.

Here are some common uses for tar. If you pass a directory or a wildcard to tar, it will include all subdirectories in the tar file by default.
Create a gzipped tar archive
tar czvf backup.tgz files-to-backup

Create a gzipped tar archive, preserving file permissions
tar czvpf backup.tgz files-to-backup

At over 23k, the current email regexp is getting pretty big. That doesn't include the nested comment
stripping, which adds just over 1k, or the domain literal (IPv4 & IPv6) rules, which add another 1k.

It's a testament to PCRE that it even runs.
