删除数组中重复字符

public static void main(String[] args) {
		String str[] = {"1","2","3","4","4","3","7","a","3"};
		//System.out.println(deleteDouble(str));
		System.out.println(deleteDouble(str));
	}
	/**
	 * 数组实现
	 * @param s
	 * @return
	 */
	public static ArrayList<String> deleteDouble(String s[]){
		ArrayList<String> a = new ArrayList<String>();
		for (int i = 0; i < s.length; i++) {
			if(!a.contains(s[i])){
				a.add(s[i]);
			}
		}
		return a;
	}

你好，首先第11行会出现数组下标越界，其次当发现S[j]与S[i]相等时，要将S[j]变成什么呢，这点我没太看懂，您能帮我解释下吗，谢谢~
