How can I organize strings by their content?

Alrro

Hello, I have a .txt file with strings. And, you see that there are words that start and end with [ and ] respectively. My question is, how can I organize strings by these words. Imagine, the first word is [duck], how can I make that all strings from that and the next [] word are related in a Hashmap?

Thanks!

Hello ! What did you try ?

GoToLoop

String str = "[duck]";
str = str.replace("[", "").replace("]", "");
println(str);
exit();

No, but what I want is to take what is after the [duck] and include put it in a HashMap.

Thanks for your fast answer

After reading the question three times, I am still unsure of what you want to do. I suggest to show a sample of text, and what is the expected result from that.

yes

I have a .txt file with strings.

please show the first ten lines. Does it look like

• [duck] swims

• [duck] is black

?

how can I make that all strings from that and the next [] word are related in a Hashmap?

do you mean all [duck] together, so there are multiple lines with the word duck? Or Do you mean every word in [] ?

are related in a Hashmap?

are related? Do you mean put them in a HashMap next to each other? hm. you could put together a class entity and one is duck? And the other is frog? And they all have fields like size, movement, color?

import java.util.Map;

String stuff = "[Foo] a b c d e [Bar] f g h [Baz] i j k l";
HashMap<String, String> stuffMap;

void setup() {
  size(100, 100);

  stuffMap = new HashMap<String, String>();

  String[] explodeLeft = split(stuff, '[');
  for (int i = 1; i < explodeLeft.length; i++) {
    String[] explodeRight = split(explodeLeft[i], ']');
    stuffMap.put(explodeRight[0], trim(explodeRight[1]));
  }

  for (Map.Entry me : stuffMap.entrySet()) {
    print(me.getKey() + " is ");
    println(me.getValue());
  }

  exit();
