There are lots of C# developers who will be fast enough to with updates that are quite often, C# has lots of thing that Java does not have. Before we get to know that C# had Generics and Lambdas in Java you can find lots of major components in Java that is not visible in C#. The top features are researched and found that most of the Java developers fail to see in C#. Clear benefits to Java users are offered by few of them while few of them are surrounded by controversy.
1) Checked Exceptions :
Exceptions are divided by Java into Checked and Unchecked during compile time, checked exceptions are conditions that are checked. An exception can be thrown by few methods for handling a try/catch block or else the exception specified must be with a throw statement. The logic is offered by the Java needs for handling at the compile time. On the contrary, there is no checked exceptions in C# and the features are not included by the architects purposefully. The discussion over having a checked exceptions is an advantage or a drawback for going close to 20 years and is still nowhere actually settled.

2) Non-Static Inner Classes :
Nested classes is present in both Java and C# but the nested classes is divided in a different way by Java into two main categories. Static nested classes can be found by you in each language which is a static member of the outer class that does not have link towards the instance methods or variables from the outer class. Without actually initiating the outer class these nested classes can be called.
3) Final keyword :
One of the defining properties of object-oriented languages is none other than Polymorphism and it will not be possible without these imaginary methods. When the functions can be overridden, a virtual method is used by any class that is inherited by it. By default every method is assumed to be virtual in Java and can be considered non-virtual with the help of final keyword. On the contrary in C# all the methods are regarded as non-virtual by default and is a direct equivalent keyword without any use.

To a class, method, or variable, the final keyword can be applied and there are similar consequences of instance in each keyword. A final variable will act similar to a constant and its value will be fixed. It is not possible to extend the final class nor it can be overridden. For being inherited from C#, a class can be avoided and it can be used with the sealed keyword. With respect to the case of non-class fields you can find two different keywords that can be used for preventing the modifications. For runtime constants, Read only can be used while constant is used for compile time constants.
4) Covariant Method Return Types :
Moreover as you can find this difference is less and the use-cases are not common, the presence of covariant return types in Java can protect you from the required for creating new methods. Mostly in C# the base class methods are overridden by the subclass method that has to sink with the name return type and argument type of the method in the base class. With respect to invariant return type, you can create a new method if you want to narrow the return type.
The return type is narrowed by the following snippet code in Java when the Clothes method is overridden in the Pants subclass For returning Jeans type which is a subtype of the clothes method.
