Below is the implementation of equals$()$ for the Point $2D$ immutable class that was discussed in lecture. Which of the indicated lines $($both the if$-$statement and true branch$)$ can be removed without impacting the behavior of this method and why? The answer may be read becaust

@override

public boolean equals $($Object other$)\{$

if $($other $==$ this$)$ return true;

if $($other $==$ nu$11)$ return false;

I$/$LINE A

if $($other$.$getClass $()$ I$=$ this. getClass $())$ return false: I$/$LINE B

Point$2$D Point $2$D$)$ other;

$$

return this. $x()==p*x()$ && this. $y()==p*y()$;
