3 ways to convert array to ArrayList

Yes. We can do it this from three ways.

1. Arrays.asList(...)
      e.g.,
             String[] array = {"value1", "value2", "value3", "value4"};
             List<String> arrayList = Arrays.asList(array);
 
2. Collections.addAll(...)
       e.g., Collections.addAll(exampleList, "Value1", "Value2" , "Value3");

3. In spring framework---> CollectionUtils.arrayToList(...)
      e.g.,
            String [] array = {"value1", "value2", "value3", "value4"};           
            List<String> arrayList = CollectionUtils.arrayToList(array);
