Both C# and Java are well-known programming languages. The first reason to support why C #is so similar to Java is: C# and Java, both inherit much of their syntax from C++. You don’t need to learn a new programming language because of simple and reuse syntax of them.
Secondly, C# is Microsoft’s version of Java!
Both of them use many recent innovations in programming language design but still C# and Java are so simple to implement in a course such as CS-112.
Furthermore, C# so similar to Java because of the following below characteristics:
Also, some things such as exception handling, memory management, and compilation (threads, IO, network, etc.) are executed in the same manner to both of them. In addition to this, these both have the easy-to-use environment and class library.
All we can say is, both the programming languages use the most productive and useful features from each other.
