If not, what is the recommended technique to initialize a Static class using an argument?Ī static class to my understanding is a class which cannot be instantiated (in c# they're called static classes, if Java has a different term for them, sorry for not being aware of it) – it's accessed through it's class name rather than an object name. A class can provide a public static factory method that can return an instance of the class e.g.
Static block can also help in reducing lines of code.
Static constructor java code#
The code inside the static block is executed only once. Static block executes when the class is loaded in the memory. Is there a way to pass arguments to a static constructor? Parameterized Constructor Constructor Overloading with static block A static block in Java is used for static initializations of a class. This is only suitable for classes that offer only static members to the caller. I'm aware of the static block, but it seems it can't take any arguments. No objects can be constructed, either by the caller or by the native class. Illegal modifier for the constructor in type M圜lass only public, protected & private are permitted. When we make a class constructor static, compiler will flash an error i.e. Actually, java static constructor concept is not there. Here, we are implementing a Java program to explain the static block and constructor. Answer: No, we don’t have static constructor in java. The constructor is called when an object of a class is created. I'm trying to initialize a static class, with an argument, and then run some more static code in that class. Java program to explain static block and constructor. A constructor in Java is a special method that is used to initialize objects.
