About Java Vs C#

After the creation of Java,  Microsoft developed the C# language   and C# is closely related to Java. Many of C#’s features directly parallel Java. Both Java and C# share the same general C++-style syntax, support distributed programming, and utilize the same object model. Though there are some differences between Java and C#, but the overall feel of these languages is very similar. If you already know C#, then learning Java will be easy and vice versa Java and C# are optimized for two different types of computing environments. C# and Java Both Languages are drew from C++. Both Languages are capable of creating cross platform portable program code.
