ArrayList Collection problem in java

[Bricklayer]

Hello,
I try to translate a program with tables list string using the ArrayList collection and from the beginning I'm falling in a stalemate that does not allow me to continue the translation:

	ArrayList list = new ArrayList (); 
	lst.add (Integer.parseInt (str [0])); 
	lst.add (Integer.parseInt (str [1])); 
	lst.add (Integer.parseInt (str [2] )); 
	lst.add (Integer.parseInt (str [3])); 
	char class = '' if (lst.get (0) <127 & & lst.get (0)> 0) (System.out.println ("Your ip address is Class A") class = 'A';)

Level error condition, if you could help me with this. Thank you.

Its been a while since I have not done java, once I'm not too sure of myself, but if I understand well your problem, you would like to replace.

int cat = Integer.parseInt (str [0]); Intl H1 = Integer.parseInt (str [1]), int H2 = Integer.parseInt (str [2]), int H3 = Integer.parseInt (str [3] )

by using an array lst?
just as in this example:

ArrayList lst = new ArrayList (); ls.add (ip.split ("\ \.")) Int cat = Integer.parseInt ((String) ls.get (0)) if (class <127 & & Class> 0 ) (System.out.println ("Your ip address is Class A") class = 'A'

and the problem in this example is that java does not cast to an element of an ArrayList to a string.
tries may be declaring your array as its lst:

<String> ArrayList lst = new ArrayList ();

if its running there Aurra probably less hassle to go from one element of a string ArrayListe then an int as you attempt to do in this line:
int cat = Integer.parseInt ((String) ls.get (0));

I tried something else:

ArrayList list = new ArrayList (); liste.add (ip.split ("\ \.")) Int category = Integer.parseInt ((String) liste.get (0)) if (class <127 & & Class> 0 ) (System.out.println ("Your ip address is Class A") class = 'A';)

Even this is not working for me. More help is appreciated. Thank you.

I think this is not possible to use the collections in this kind of program, given what will accept any kind and I do not know how to make distinctions between types in the case of chained lists.

It obviously just the problem that Java can not be cast to the contents of your list is like
"java.lang.String" in a type "java.lang.String".
You should try can be put "lst.get (0)" in a String variable means by causing something like:
String = temp (lst.get (0)). ToString ();
and after you do:
int category = Integer.parseInt (temp);
