hi, everyone. i have a problem with writing from a list. i've one such as
LinkedList list =new LinkedList();
list.add("one");
list.add("two");
System.out.println(list);
so i'm achieving such as that:
[one,two]. is there any way to achieve such as that:
one, two <without those brackets?please for any help,
king regards
Either write your own method, or use String's replace or replaceAll method to get rid of them.
You are getting that beacuse you are printing the list itself. Try using a loop and going through the whole list using the get method see below:
LinkedList<String> list = new LinkedList<String>();
list.add("one");
list.add("two");
System.out.println(list);
for(String listVal : list){
System.out.print(listVal+ " ");
}
i've tried it it works, thanks but one more thing from antoher subject:
i have string: "abracadabra"
now i'm checking if my string has "abra"
if(string.indexOf("what should i put here")>-1) then....
what should i put there, i'm too good in regex, thanks for advice

Are you checking whether the beginning of the string has "abra" or whether "abra" is anywhere in the string?
