C# Vs Java | Key Differences Between C# and Java
Take a look at this section to fully understand the meaning of C# and Java.
What is C#?
C# (pronounced “see sharp”) is a modern, object-oriented programming language that was developed by Microsoft as part of its .NET framework. It was designed to be a simple, easy-to-learn language that combines the best features of C++ and Java. C# is a versatile language that can be used to develop a wide range of applications, from desktop software to web applications to games. It is widely used in the development of Windows applications and is also supported on other platforms such as Linux and macOS through the .NET Core framework. C# has a rich library of pre-built classes, making it an efficient language for developing complex applications.
What is Java?
Java is a popular, general-purpose programming language that was originally developed by Sun Microsystems in the mid-1990s. It is an object-oriented language that is designed to be platform-independent, meaning that code written in Java can run on any computer or operating system that has a Java Virtual Machine (JVM) installed. Java is commonly used for developing web applications, mobile apps, and enterprise software. It has a large and active community of developers, and there are a wealth of libraries and frameworks available to help programmers develop robust and efficient applications. Java is known for its simplicity, readability, and ease of use.
