ArrayList list = new ArrayList();
list.add(1);
list.add(\"Java\");
list.add(3.14);
System.out.println(list.toString());

    Using Java 8 you can do:
    


    List list = ...;
List strList = list.stream()
                           .map( Object::toString )
                           .collect( Collectors.toList() );
