This means that only one instance of that static member is created which is shared across all instances of the class..
Why do we use static void main in Java?
When java runtime starts, there is no object of the class present. That’s why the main method has to be static so that JVM can load the class into memory and call the main method. If the main method won’t be static, JVM would not be able to call it because there is no object of the class is present.
Is String args necessary in Java?
The Java runtime system looks specifically for a method with a single String type parameter, because it wants to pass the parameters to your main method. … If you want to treat the (string) command line parameters as integers or booleans, you are expected to do the conversion yourself.

Why methods are declared static in Java?
You should use static methods whenever, The code in the method is not dependent on instance creation and is not using any instance variable. A particular piece of code is to be shared by all the instance methods. The definition of the method should not be changed or overridden.
Why we Cannot override static method?
Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).
What is the example of static?
