The answer is option 1 arr.length.
Explanation:
In java arr.length gives the correct number of elements in the array.The length is function is only applicable for arrays.
The length() method is applicable for strings.
arr.length-1 will give 1 element less.
There is no .size for arrays in java.
So we conclude that arr.length is correct way of getting the number of elements in one dimensional array arr.

Answer:
Explanation:
The following function/program is written in Java. It asks the user for a sentence as an input and then splits that sentence into an array of words. Then it creates an arrayList for all of the unique words, comparing each word in the sentence with all of those in the ArrayList. If a word is found in the ArrayList it cancels the loop and moves on the next word in the sentence. Finally, it counts all of the unique words in the ArrayList and prints that total to the screen.
public static void uniqueWords() {
Scanner in = new Scanner(System.in);
System.out.println("Enter a sentence:");
String sentence = in.nextLine();
String words[] = sentence.split(" ");
ArrayList<String> uniqueWords = new ArrayList<>();
for (int x = 0; x < words.length; x++) {
boolean exists = false;
for (int i = 0; i < uniqueWords.size(); i++) {
if (words[x].equals(uniqueWords.get(i))) {
exists = true;
break;
}
}
if (exists == false) {
uniqueWords.add(words[x]);
}
}
System.out.println(uniqueWords.size());
}
