Java vs C#
C# is a general-purpose, modern and object-oriented programming language pronounced as “C sharp”. It was developed by Microsoft led by Anders Hejlsberg and his team.
Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented etc. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture.
Below are some major differences between C# and Java:
| Feature | C# | Java |
|---|---|---|
| Operator Overloading | C# supports operator overloading for multiple operators. | Java does not support operator overloading. |
| Runtime Environment | C# supports CLR(Common Language Runtime). | Java supports JVM(Java Virtual Machine). |
| API Control | C# API are completely controlled by Microsoft. | Java API are controlled by open community process. |
| Public Classes | In C#, there can be many public classes inside a source code. | In Java there can be only one public class inside a source code otherwise there will be compilation error. |
| Checked Exceptions | C# does not supports for checked exception. In some cases checked exceptions are very useful for smooth execution of program. | Java supports both checked and unchecked exceptions. |
| Platform Dependency | C# code is windows specific. Although Microsoft is working to make it global but till now the major system does not provide support for C#. | Java is a robust and platform independent language. Platform independency of Java is through JVM. |
| Pointers | In C# pointers can be used only in unsafe mode. | Java does not supports anyway use of pointers. |
| Conditional Compilation | C# supports for conditional compilation. | Java does not supports for conditional compilation. |
| goto statement | C# supports for goto statement. | Java does not supports for goto statement. Use of goto statement will cause error in Java code. |
| Structure and Union | C# supports structures and unions. | Java doesn’t support structures and unions. |
| Floating Point | C# does not supports strictfp keyword that means it result of floating point numbers may not be guaranteed to be same across all platforms. | Java supports strictfp keyword that means its result for floating point numbers will be same for various platform. |
