Given the following code, which statement is correct?

class Sample $\{$ int add$($int x$,$ int y$)\{$ return x$+$y;$\}//$ form $1$ String add$($String x$,$ String y$)\{$ return $($x$+$y$)+""$; $\}//$ form $2$ double add$($int x$,$ int y$,$ int z$)\{$ return x$+$y$+$z; $\}//$ form $3$ void add$($int x$)\{$ System.out.print$($x$)$; $\}//$ form $4\}$

Group of answer choices

form $1$ has a conflict with form $2$ because parameters in form $2$ are different from parameters in form $1.$

form $1$ has a conflict with form $3$ because the number of parameters in form $3$ is not equal to that of form $1.$

There is no conflict among these four forms.

form $2$ is the one that will cause conflicts with others because String is not a primitive data type.

form $4$ is the one that will cause conflicts because it is the void type.
