I want to convert this String into an ArrayList
String
["one","two","three"]
I used this method
List<String> logopath = Arrays.asList(pos.split("\\s*,\\s*"));
I get this output from logopath
0 = "["one""
1 = ""two""
2 = ""three"]"
But I want the output of logopath to be like this:
0 = "one"
1 = "two"
2 = "three"
Your string is actually valid JSON, so I would suggest using a JSON parser here:
String input = "[\"one\",\"two\",\"three\"]";
Gson gson = new Gson();
JsonArray items = gson.fromJson(input, JsonArray.class);
List<String> list = new ArrayList<>();
for (JsonElement item : items) {
String num = item.getAsString();
list.add(num);
}
System.out.println(list);
JsonArray but I need List or Arraylist
List<String> list = new Gson().fromJson( input, JsonArray.class ).stream().map( JsonElement :: getAsString ).toList()
It can be achieved as below,
String input[] = {"one","two","three"};
List<String> arrList = new ArrayList<>();
for(String s:input){
arrList.add(s);
}
System.out.print(arrList);
string not string[] , so I cannot apply it.
