class StringSet

{

ArrayList<String> arraylist; //a reference variable of ArrayList of generic type String

//A no argument constructor.

public StringSet()

arraylist=new ArrayList<String>(); //instantiating the ArrayList object

int size()

return arraylist.size(); // size() method which gives the number of elements in the list

}

//An accessor that returns the total number of characters in all of the Strings that have been added to this StringSet object.

int numChars()

{

int sum = 0;

for(String str:arraylist) //for-each loop; can be read as for each string in arraylist

//An accessor that returns the number of Strings in the StringSet object that have exactly len characters.

int countStrings(int len)

int count = 0;

for(String str:arraylist)

if(str.length() == len)

count++;

A search will _____ determine the index of the goal.
Lapatulllka [165]

Answer:

The correct answer is C. Sometimes.

Explanation:

A database index is a structure that aims to speed up selections and selective operations on a database. An index reduces the number of comparisons required to find one or more database records. This avoids having to perform a so-called full table scan, whereby all records in the table have to be run through sequentially.

Therefore, if the search does not focus correctly on the necessary data, this search will not always determine the index of the goal. Therefore, the user must correctly handle the search keywords to collaborate with the system.
