Answer 1

import java.util.ArrayList;

import java.util.LinkedHashSet;

public class RemoveDuplicate

{

public static void main(String[] args)

{

ArrayList<Integer> duplicateElements = new ArrayList<Integer>();

duplicateElements.add(10);

duplicateElements.add(3);

duplicateElements.add(3);

duplicateElements.add(5);

duplicateElements.add(6);

duplicateElements.add(3);

duplicateElements.add(2);

  

ArrayList<Integer> uniqueElements = new ArrayList<Integer>();

  

for(Integer ele: duplicateElements)

{

if(!uniqueElements.contains(ele))

uniqueElements.add(ele);

}

  

System.out.println("Duplicate element in List: " + duplicateElements);

System.out.println("Unique element in List: " + uniqueElements);

}

}
