    public static void main(String[] args) {
        new LovePureImpure();
        Pure pure = null;
        Impure impure = new Impure();
        pure = new Pure();
class Pure {
    static {
        System.out.println("I am pure Love");
    public Pure() {
        System.out.println("I am impure Love disguised as pure Love");
class Impure {
    public Impure() {
        System.out.println("I am impure Love");

Ans is C..
here we have three classes

LovePureImpure and Pure and Impure

static Block:

static block wil execute when the class loads first wil execute only once..class loading means (Accessing static variable or calling static method or creating instance or class.forName("ClassNam"))

in the example
main method(static) in  LovePureImpure class wil call so that static block in that class wil get executed("Love is neiher Pure nor impure")
in main method we are creating instnce for the this class so that constructor wil invoked and printed as "Love is purely impure and impurely pure"

next we are creating refernce for the class Pure creating reference didnt cal anything next we are creating instance for the impure class so that constrcotr wil cal and prints "I am impure Love"

here we are creating the object for the Pure class so that static block in Pure class wil get printed "I am pure Love" next constrcutor wil Invoked

because firstly static method will be called before main class ececution i.e. "Love is neither pure nor impure".

after that class  LovePureImpure will be called which contains " Love is purely impure and impurely pure"

after that class impure executed thatcontains " I am impure Love"

after ececution of impure method , class pure will be called which contain "I am pure Love  " will be executed...

and after again pure class will be executed and " I am impure Love disguised as pure Love"....

Ans is C.
In above Example concept of Static block is used.If you have executable statements in the static block, JVM will automatically execute these statements when the class is loaded into JVM.

Execution Order:

----LovePureImpure is First Class that  gets loaded and static block gets executed which prints  --> "Love is neither pure nor impure"

---Object of LovePureImpure class is created which calls it's constructor which in turn prints -> "Love is purely impure and impurely pure."

---Reference of pure class is created.

---Object of Impure class is created which calls its constructor which prints -> "I am Impure Love"

---Reference of pure class is allocated memory which executes static block i.e. " I am pure Love " gets printed.

---After that constructor of Pure Class is created which prints "I am Impure Love disguised as pure Love."
