 public static void main(String[] args) {
		// TODO Auto-generated method stub
		ArrayList newarry=new ArrayList();
		newarry.add("abc");
		newarry.add("def");
		newarry.add("xyz");
		newarry.add("232");
		newarry.add("121");
		
//		Iterator ite=newarry.iterator();
//		while(ite.hasNext()){
//			System.out.println(ite.next());
//		}
		
//		for(int i=0;i< newarry.size();i++){
//			System.out.println(newarry.get(i));
//		}
		
//		for(String i:newarry){
//			System.out.println(i);
//		}

		//newarry.remove(2);
		//newarry.removeAll(newarry);
		for(String i:newarry){
			System.out.println(i);
		}
	}

}

output:
abc
def
xyz
232
