Java does not permit to declare a constructor as static. Following are the reasons.
1. Static means for the same class. For example, static methods cannot be inherited.
2. With static, "this" reference (keyword) cannot be used. "this" is always linked to an object. A constructor always belongs to some object.
3. If a constructor is static, an object of subclass cannot access. If static is allowed with constructor, it is accessible within the class but not by subclass.
The following program raises compilation error.
public class Demo
{
public static Demo()
{
System.out.println("Hello 1");
}
public static void main(String args[])
{
Demo d1 = new Demo();
}
}

Observe, the compiler error message. It says, static is not allowed with constructor.
What other access modifiers a constructor cannot be?
