public class Q2 {
 static int class_var = 2;
 
 public Q2(){
  class_var = 5;
 }
 public static void main(String args[]){
  System.out.println(class_var);
 }
}

a. 2
b. 5
c. Compile time error
d. None of the above.

Answer:

A is the correct choice. class_var is declared as a static variable and initialized to 2. When main is called, it's value would be 2 since there is no object of the class created, so constructor is not called.
