What is C# ?
- C# is a general purpose programming language that initially appeared in 2000, as part of Microsoft’s .NET initiative.
- It was designed for the Common Language Infrastructure (CLI)—an open specification developed by Microsoft and standardized by ISO as well as ECMA.
- C# applications are compiled into bytecode that can be run on implementations of the CLI.
What is Java ?
- The Java released by Sun Microsystems in 1995, Java is also a general purpose programming language that was designed with the specific goal of allowing developers to “write once, run anywhere.”
- Java applications are compiled into bytecode that can be run on implementations of the Java Virtual Machine (JVM). Like CLI, JVM helps bridge the gap among source code and 1s and 0s that the PC understands.
