How similar is C# to Java?

Brand new to C# as of today but got the incentive to learn it at my new internship. After the first video, "public static void Main (string[] args)" instantly popped out. Obvious to anyone as familiar with java as I am. Going further with C# is there any advice as to the similarities and differences? And/or anything else I should know about the language before I dive in? Thanks

hey there!

Well major similaritie is that both are based on OOP concept, Java is more concerned towards enterprise based functionality, whereas C# is more conecerned towards application and subject based.

Similarities of java and C#

All Objects are References
Both C# and Java are Type-Safe Languages
Garbage Collection
Both C# and Java Are "Pure" Object-Oriented Languages
C# and Java allow only single inheritance.
Built-in Thread and Synchronization Support
Formal Exception Handling
Built-in Unicode Support

On the syntax level, Java was influenced by Smalltalk, while C# tried to stay closer to C/C++ (eg: compare Java's extends and implements with C#'s : notation) and took a vague inspiration from VB on those concepts that weren't mappable to C/C++ (example: property syntax).

On the features level, C# 1 was definitely close to Java. Among the few differences they had, I'd highlight C#'s support for "unsafe" code (including pointers) and for delegates; and Java's controversial throws. This makes sense, since one of the goals of C# was to become an alternative to Java.

Many language features differ heavily on implementation details. For example, enums are very C'ish on C#, but are full objects in Java; or generics are implemented on the IL-level in C#, but in Java are dealt with via type erasure (neither is really close to C++'s templates besides syntax).

On the API level, they are worlds apart. C# relies on the .Net Framework, which was built on Microsoft's experience with the Visual Studio family of products (and thus is significantly Windows-oriented), while Java's Class Library was built, IIRC, from scratch, and heavily evolved over time.
