Analyze the following code:

public class Test $\{$

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

NClass nc $=$ new NClass$()$;

nc$.$t $=$ nc$.$t$++$;

$\}$

$\}$

class NClass $\{$

int t;

private NClass$()\{$

$\}$

$\}$

Group of answer choices

The program does not compile because the parameter list of the main method is wrong.

The program compiles, but has a runtime error because t has no initial value.

The program has a compile error because the NClass class has a private constructor.

The program compiles and runs fine.

Group of answer choices

Constructors must have the same name as the class itself.

Multiple constructors can be defined in a class.

Constructors are invoked using the new operator when an object is created.

Constructors do not have a return type, not even void.
