Static variables or function provides global view to the application that is u can access a static variable with one or more than one objects of a single class without loosing i.e. reinitializing its value.

What is static inner class?
An inner class declared as static is treated as if it were a normal top-level class.
What happens when you declare class as a static in Java?
Declaring an inner class static means that class only has access to the "outer" class public and private static fields. A non-static inner class has access to the outer class's instance data. Top-level classes cannot be declared static. The advantage of a static inner class is that it doesn't need an instance of the containing class to work and it's bytecode class size is smaller for that reason - less overhead.
Which one executed first static block or static methods in java?
Static Blocks are always executed first. A static block is executed when your class is charged but a static method is executed only when is called, therefor first the class is charged and then is executed a method.
What is static java most commonly used for?
Static java method is the same as a static variable. They belong to a class and not an object of that class. If a method needs to be in a class, but not tied to an object, then one uses static java.
Static keyword in java?
A Static method in Java is one that belongs to a class rather than an object of a class. Normal methods of a class can be invoked only by using an object of the class but a Static method can be invoked Directly. Example: public class A { ..... public static int getAge(){ .... } } public class B { ..... int age = A.getAge(); } In class B when we wanted the age value we directly called the method using the instance of the class instead of instantiating an object of the class. Tip: A static method can access only static variables. The reason is obvious. Something that is common to a class cannot refer to things that are specific to an object...
What is static class?
A static class is a class where all the members are declared static.
Why toplevel class cannot be static?
A toplevel class certainly can be static. Static has nothing to do with the level of a class.
Are the methods or members of static class static?
A static class may or may not have static members. Adding the static keyword to the class definition won't change this. Note that an inner class which is not static may not contain static members (unless those members are also declared final).
How is dynamic initialization of objects is achieved?
by creating class as an static class

What is the static variable in the class in c?
A static member variable is local to the class rather than to an object of the class.

What is static variable in the class for c plus plus?
Static member variables are local to the class. That is, there is only one instance of a static member variable, regardless of how many objects are instantiated from the class. As such, they must be declared inside the class, and defined outside of the class.
Can you make a class static without using static keyword?
No.
