In Java programming,

class Overload

$\{$

void ovlDemo$()$

$\{$

System.out.println$("$No parameters"$)$;

$\}$

$//$ Overload ovlDemo for one integer parameter.

void ovlDemo$($int a$)$

$\{$

System.out.println$("$One parameter: $"+$ a$)$;

$\}$

$//$Overload ovlDemo for two integer parameters.

int ovlDemo$($int a$,$ int b$)$

$\{$

System.out.println$("$Two parameters: $"+$ a $+""+$ b$)$;

return a $+$ b;

$\}$

$//$Overload ovlDemo for two double parameters.

double ovlDemo$($double a$,$ double b$)$

$\{$

System.out.println$("$Two double parameters: $"+$ a $+""+$ b$)$;

return a $+$ b;

$\}$

$\}$

class OverloadDemo

$\{$

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

$\}$

$\}$ A$.$ How does void ovlDemo$()$ and int ovlDemo$()$ impact the output of the program?

B$.$ What will the program output when the method is overloaded with the same type and numbers of parameters?
