    public static void main(String[] args){
    ArrayList al = new ArrayList();
    al.add("abc");
    al.add('a');
    al.add('b');
    al.add('a');
    al.add("abc");
    al.add(10.3);
    al.add('c');
    al.add(10);
    al.add("abc");
    al.add(10);
    System.out.println("Before Duplicate Remove:"+al);
    for(int i=0;i
