Java get a specific data in jsonarray

Question

{"a":"AAA","b":32.4,"c":34.65},
{"a":"AAM","b":10.8,"c":11.55}

I use JSONArray to get jsonarray above. I want to use this code get data b:10.8 if a:AAM .

public static void main(String[]args) throws Exception{ 
  String get = sql.getQuote();
  JSONArray jsonarray = new JSONArray(get);
  for (int i = 0; i<jsonarray.length();i++){
    JSONObject obj = jsonarray.getJSONObject(i);
    String symbol = obj.getString("a");
    if (symbol.equals("AAM")){
      double price = obj.getDouble("b");
      System.out.println(price);
    } else { 
      break;
    }
  }
}

Please help me to fix it. Thank you in advance.

Answer 1

The problem is with else statement in for-loop .

Remove else block ie

 else { 
         break;
      }

In your code, else block stops the for-loop on very first iteration. Because here "a":"AAA" . Since the condition if (symbol.equals("AAM")) is false so else block is executing which further breaks the loop iteration.

Answer 2

The problem is the break in the else, just take it out. If anywhere, it would be most appropriate in the if part:

if (symbol.equals("AAM")) {
    System.out.println(obj.getDouble("b"));
    break; // or leave it out if there might be a second AAM entry
}
