Try below code :

 public static void main(String[] args) throws Exception{
     List l = new ArrayList();
     l.add("abc");
     l.add("xyz");
     l.add("test");
     l.add("test123");
     System.out.println(l);
     List dl = new ArrayList();
    for (int i = 0; i < l.size(); i++) {
         String a = l.get(i);
         System.out.println(a); 
         if(a.equals("test")){
             dl.add(a);
         }
    }
    l.removeAll(dl);
     System.out.println(l); 
}

your output :

 [abc, xyz, test, test123]
abc
xyz
test
test123
[abc, xyz, test123]
