Does all Java class need a constructor?

All classes have constructors by default : if you do not create a class constructor yourself, Java creates one for you. However, then you are not able to set initial values for object attributes.

Java does not actually require an explicit constructor in the class description. If you do not include a constructor, then the Java compiler will create a default constructor with an empty argument .11 Ağu 2016

Answer: Yes, C# class without constructor is possible . In fact, we can have a class without any constructor in C#. If we don’t declare any constructors in a class, the compiler automatically provides a public parameter less constructor. And it is ok to instantiate the class without constructor.
