Skipping element addition in list

[Eshwar Prasad]

I have a requirement to add elements from one list to another and during time if i encounter AB value second time, i have to add it in new list and not in current list, test. So I used the keyword continue if the values AB occurs. I am not getting the expected answer. My out put in list test should be as [9B, 9Y, AB, BC, BC]. Can any one please help me.

package com.test;
import java.util.*;
public class Testvector {
	public static void main(String[] args) {	
		List al=new ArrayList();
		al.add("9B"); al.add("9Y"); al.add("AB"); al.add("BC"); al.add("AB"); al.add("BC");
		List test=new ArrayList();
		for (int i=0;i<al.size();i++){
			if(test.contains("AB"))continue;
			test.add(al.get(i));
			System.out.println(test);
		}
	}
}

After you add "AB" for the first time, your second list will contain "AB" for the remainder of the loop. It will therefore skip both "BC" values as well.
