Difference between static and non static constructor?

Answer 1

A static constructor is used to do anything you need done before any static methods are called such as static variable initialization. In Java (as in C#) when a static constructor is called is non-deterministic but will always be called before a static method on the same class.

Answer 2

JavaThere is really no such thing as a static constructor in Java. The closest thing that comes to mind is a factory class, which calls a private constructor when a static method is called.

class A {
// This private constructor can't be called by any other class.
private A() {
}

// Here is your "static" constructor
public static A getInstance() {
return new A();

}

}

Answer 3

Static members are local to the class rather than to instances of the class. In other words, they are shared amongst all instances of the class. Moreover, since they are static, they exist even when no instances of the class exist. Thus static member methods and friends of the class can access static member variables and external functions can access the public static members, without instantiating an object of the class.

Answer 4

No, it's not. Constructors operate with pointers when fields by default operate with values.

Answer 5

Static members are loaded when the class creates...while others only when an instance of that class creates...
