What is wrong in the following code?

class TempClass

int i;

public void TempClass$($int j$)($

int $i=j$;

$\}$

$\}$

public class C

public static void main$($String$[]$ args$)($

TempClass temp $=$ new TempClass $(2)$;

$\}$

$\}$

A$.$ The program has a compile error because TempClass does not have a default constructor.

B$.$ The program has a compile error because TempClass does not have a constructor with an int argument.

C$.$ The program compiles fine, but it does not run because class $C$ is not public.

D$.$ The program compiles and runs fine.

Which of the following statements are true?

A$.$ Local variables do not have default values.

B$.$ Data fields have default values.

C$.$ A variable of a primitive type holds a value of the primitive type.

D$.$ A variable of a reference type holds a reference to where an object is stored in the memory.

E$.$ You may assign an int value to a reference variable.

Analyze the following code.

public class Test

int $x$;

public Test $($String t$)($

System.out.println $("$Test$")$;

$\}$

public static void main$($String$[]$ args$)($

Test test $=$ new Test$()$;

System.out.println $($test$.$x$)$ ;

$\}$

$\}$

A$.$ The program has a compile error because System.out.println method cannot be invoked from the constructor.

B$.$ The program has a compile error because $x$ has not been initialized.

C$.$ The program has a compile error because you cannot create an object from the class that defines the object.

D$.$ The program has a compile error because Test does not have a default constructor.

State weather the following statements is True or False:

$[2$

Marks$]$

Two or more references can refer to the same object.

Assigning an ancestor object to a reference is considered to be a widening $()$ conversion and must be done with a cast.

Polymorphic references are resolved at compile$-$time; this is called dynamic $()$ binding.

A polymorphic reference $v$ is declared as class $C,$ but unless $C$ is final or base $()$ type, $v$ can refer to an object of class $C$ or to an object of any class derived from $C.$
