I have a string containing information in the following format:
Maltese Age: 2 Price: $500
https://images.google/image
Staffy Age: 1 Price: $500
https://images.google/image
Yorkie Age: 2 Price: $300
https://images.google/image
My goal, is to turn the above into something like this:
Dogs:
{
"dog": "Pomeranian",
"info": {
"url": "https://images.google.com/image",
"age": 2,
"price": 1000
}
And of course loop around back and fourth for all of the pets I have in the string.
If you use regular expressions you can get the values like this:
JSONArray arr = new JSONArray();
Matcher m = Pattern.compile("([^ \\r\\n]*) Age: ?(\\d+) Price: ?\\$?(\\d+(?:\\.\\d*)?)\\r?\\n(http[^ \\r\\n]*)").matcher(str);
while (m.find()) {
String dog = m.group(1);
String age = m.group(2);
String price = m.group(3);
String url = m.group(4);
// Add to a JSON object using your preferred JSON library
// Example:
JSONObject obj = new JSONObject();
obj.put("dog",dog);
JSONObject info = new JSONObject();
info.put("age",age);
info.put("price",price);
info.put("url",url);
obj.put("info",info);
arr.put(obj);
}
There are probably multiple ways to do it, but one way to do it may be something as follows.
You can start by splitting your text into lines.
var lines = text.split("\n");
Then you know that odd lines are URLs, and even lines are dog information.
List<JsonObject> objects = new ArrayList<>();
for(int i=0; i < lines.length; i++) {
var line = lines[i];
if(i % 2 == 0) {
// apply regex solution given in the other answer
// to extract the dog information
} else {
url = line;
// since json objects are complete on odd lines
// build json and add it to the list
var jsonObject = ...;
objects.add(jsonObject);
}
}
