Simple

Java derives its syntax from C and object oriented features from C++.
If you are good in C and C++ programming then you can learn Java easily. Hence Java is Simple.

Secure

Java provides its own execution environment and hence do not allow any malicious program to access other parts of computer.
Java Virtual Machine (JVM) verifies the code before execution (sandbox security).

Portable

Java is platform independent i.e. Write Once and Run Anywhere (WORA).
When java program is compiled a .class file (bytecode) is created. This .class file can run on any platform (linux, windows, mac). You just need JVM of that platform.

Robust

Java is called as robust because of following two features:

Automatic Memory Management
Automatic Exception Handling

Object-Oriented

Java is object oriented programming language same as C++.
It means focus on the data and methods that manipulate that data instead of taking care of procedures.

Multithreaded

Java supports multithreaded programming.
It allows you to write programs that do many things simultaneously.

Architecture-Neutral

Java is machine independent.
It was made with goal “write once; run anywhere, anytime, forever”.

Interpreted

Java enables the creation of cross-platform program i.e. bytecode.
This code can be executed on any platform that has JVM.

High Performance

Java bytecode can be easily executed on any machine for very high performance by using a just-in-time (JIT) compiler.

Dynamic

Java programs carry with them substantial amounts of run-time type information that is used to verify and resolve accesses to objects at run time.

Distributed

Java enables the creation of distributed applications which can be accessed on the internet.

Swift A New Programming Language Introduced by Apple For iOS and OS X Development

Swift is an object-oriented programming language for iOS and OS X development which is recently introduced by Apple at its WWDC 2014. It is intended to coexist with Objective-C, the current programming language for Apple operating systems. Swift is designed to be more resilient against erroneous code. It is built with the LLVM compiler.

Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible, and more fun. Swift’s clean slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, is an opportunity to reimagine how software development works. On June 2, 2014, the WWDC conference app became the first publicly released Swift app.

Example code

let people = ["Anna": 67, "Beto": 8, "Jack": 33, "Sam": 25]

for (name, age) in people {

println("(name) is (age) years old.")

}

Some awesome features of Swift Programming Language

Safe

Swift pairs increased type safety with type inference, restricts direct access to pointers, and automatically manages memory—making it easy to create secure, stable software.

Modern

Swift includes optionals, generics, tuples, and other modern language features. Inspired by and improving upon Objective-C. Swift code feels natural to read and write.

Powerful

Take advantage of powerful pattern matching in Swift to write simple, expressive code. Format strings naturally with string interpolation. Use frameworks like Foundation and UIKit directly from Swift.

Interactive

Use playgrounds to experiment with new technologies, analyze problems, and prototype user interfaces

Fast

The Swift compiler applies advanced code analysis to tune your code for performance, letting you focus on writing great apps instead of on implementing complex optimizations.
