Question
Complete the file above using JAVA.
Write a method that removes adjacent duplicates from an array list. Complete this code. Use the following file: Tester.java import java.util.Arrays; import java.util.ArrayList; public class Tester {public static void main(String[] args) {ArrayList words1 = new ArrayList(Arrays.asList("Typing a a word twice is is a common mistake", split(" "))); ArrayListUtil.removeAdjacentDuplicates(words1); System.out.println(words 1); Systern.out.println("Expected: [Typing, a, word, twice, is, a, common, ArrayList words2 = new ArrayList(Arrays.asList("Typing a word three times is is is not so common".split(" "))); ArrayListUtil.removeAdjacentDuplicates(words2); System.out.println(words2); System.out.println("Expected: [Typing, a, word, three, times, is, not, so, common] mistake]"); so, common]");");}} Complete the following file: ArrayListUtil .java import java.util.ArrayList; public class ArrayListUtil {/** Removes adjacent duplicates from an array list of strings. @param word an array list of strings */public static void removeAdjacentDuplicates(ArrayList words) {...}}}Explanation / Answer
import java.util.ArrayList;
public class ArrayListUtil
{
public static void removeAdjacentDuplicates(ArrayList<String> arr){
for(int i=arr.size()-1; i>0; i--){
if(arr.get(i).equals(arr.get(i-1)))
arr.remove(i);
}
}
}
import java.util.Arrays;
import java.util.ArrayList;
public class Adventure
{
public static void main(String[] args)
{
ArrayList<String> words1 = new ArrayList<String>(Arrays.asList(
"Typing a a aword twice is is a common mistake".split(" ")));
ArrayListUtil.removeAdjacentDuplicates(words1);
System.out.println(words1);
System.out.println("Expected:[Typing, a, word, twice, times, is, not, so, common]");
ArrayList<String> words2 = new ArrayList<String>(Arrays.asList(
"Typing a a aword three is is a common mistake".split(" ")));
ArrayListUtil.removeAdjacentDuplicates(words2);
System.out.println(words2);
System.out.println("Expected:[Typing, a, word, three, times, is, not, so, common]");
}
}
