Question

Language: Java

I am attempting to find a way to delete over 2,400 lines of a certain code... I am trying to delete every line except for the bolded lines... Remember each time this code occurs the values may be different. I WOULD LIKE THE FULL CLASS FILE READY TO RUN. The file is called "itemdef.txt" it will be located in the same folder.

This is what the code looks like:

{
"id": 9,
"name": "Different Names",
"desc": "Different Descriptions.",
"value": different values,
"dropValue": 0,
"bonus": [
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0
],
"slot": -1,
"fullmask": false,
"stackable": true,
"noteable": true,
"tradable": true,
"wearable": false,
"showBeard": true,
"members": true,
"twoHanded": false,
"requirements": [
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,

]
},

Thank you very much :)

Explanation / Answer

Hi I first read your string then convert into json and perform remove method. Please test it. You need json jar.

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.text.ParseException;
import java.util.Scanner;

import org.json.JSONObject;

public class ReadText {
  
   public static void main(String[] args) throws IOException, ParseException {
      
       Scanner sc = new Scanner(System.in);
       //System.out.print("Enter filename: ");
       //String fileName = sc.next();
      
       FileReader fr = new FileReader("itemdef.txt");
       BufferedReader br = new BufferedReader(fr);
      
       String finalJson = "";
       String line = "";
      
       while((line =br.readLine()) != null){
           finalJson += line;
       }
      
       br.close();
       fr.close();
      
       // converting into json
       JSONObject obj = new JSONObject(finalJson);
      
       obj.remove("id");
       obj.remove("requirements");
      
      
       System.out.println(obj.toString());
      
   }

}
