下列程序的功能是统计字符串中“array”的个数,在程序的空白处应填入的正确选项是( )。public class FindKeyWords{ public static void main(String[]args) { String text = An array is a data structur that stores a collection of +values of the same type. You access each individual value +through an integer index. For example,if a is an array +of inergers,then a[i] is the ith integer in the array.; int arrayCount=0; int index=-1; String arrayStr=array; index=text.indexOf(arrayCount); while(index ______ 0) { ++arrayCount; index+=arrayStr.length(); index=text.indexOf(arrayStr,index); System.out.println(the text contains+arrayCount+arrays); } }}
