QUESTION $3$ Analyze the following code. public class Test public static void main$($String$[]$ args$)\{$ int$[]$ x $=$ new int $[3]$; System.out.println$("$x$[0]19"+$ x$[0])$; $1$ The program has a runtime error because the array elements are not initialized. The program has a compile error because the size of the array wasn't specified when declaring the array. The program has a runtime error because the array element x$[0]$ is not defined. The program runs fine and displays x$[$O$)$ is $0.$ QUESTION $4$ Don't worry about what this class does. We're asking about Java language elements. Select the members of this class $01$: public class StrCharCounter $02$:$\{03$: $04$ private ArrayList store $=$ new ArrayListo $05$: private int size $=0$; $06$: $07.$ public boolean add$($String sToAdd$)08$: $09$: size$++$; $10$: if $($Istore$.$contains$($sToAdd$))11$: return store.add$($sToAdd$)$: $12$: else $13$: return false; $14$: $15$: $16$: public int calcTotalLength$()17$: $18$: intcnt $-0,19$: for $($int i $=0$; i $<$ size; i$++)20$: $\{21$: cnt $+=$ store.get$($i$).$length$()$; $22$: $23$: return cnt: $24$:$>25$:$)$ StrCharCounter O store O size O add calcTotalLength O cnt This class has no members
