Comparison of C Sharp to Java Guide, Meaning , Facts, Information and Description

This is a comparison of the C# programming language to the Java programming language.

Similarities

• Both languages were designed to be object oriented from the ground up.
• Both languages rely on a virtual machine, in the case of C# the .NET framework.
• Both languages have syntax rules which catch a large number of common programming errors (related to initialization, etc.).
• Both languages include synchronization.
• Both include garbage collection.

• Tied more closely to the Windows operating system, making for better performance in OS-specific tasks such as user interface.
• The .NET framework already supports a much larger number of languages, making for better cross-language compatibility.
• Allows the use of pointers in a relatively safe way, and certain language features ensure this functionality is not misused accidentally.
• Better support for arithmetic by including more primitive types and functionality to catch arithmetic exceptions.
• Includes a large number of notational conveniences over Java, many of which, such as operator overloading and user-defined casts, are already familiar to the large community of C++ programmers.
• Boxing and unboxing of value types, allowing numbers to be handled as an object.
• Includes an enhanced for loop. (Java will include this feature in version 1.5)
• C# is defined by ECMA and ISO standards, whereas Java is proprietary.

• Some would argue that C# is under too much control by Microsoft, making it a poor choice in the long run.
• C# can take longer to learn.

• Already implemented on a larger number of platforms, making for better cross-platform compatibility.
• More mature, meaning a lot of problems have already been worked out, and more code is already widely available.
• Language is simpler, making compile-time optimizations easier.
• Method invocation model is simpler, making it easier to implement and at times easier to read.

• Does not include operator overloading, making it ill-suited for scientific programming.
• The lack of pass-by-reference for primitive types makes certain procedural programming tasks awkward.
