To solve the problem just now exchange "final" with "static". Ex: class A { static int x; { x= 23+27; } public static void main(String arts[]) { A ob = new A(); System.out.println(x); } }

x is non static variable. so you can't refer it in a static method. you have to declare it as static.

Nothing, an error as you can refer to x from an static content

replace final by static then Ans is 50 after creating the object, constructor is invoked and object is initialised.

There are two error in this code: You referenced non-static constant (x) in static method. Final is a keyword that describes your entity is a constant, that means you can't change its value. So, an assignment to x is irrelevant. To solve the problem change your entity to a variable by removing final keyword and make it static to call it from a static method by adding static keyword. Ex. static int x; That's all.
