I need to modify a particular value of a key in my json file, it is a nested JSON file and i have traversed till that key value pair but i'm not able to modify the value and don't know how to write back to the json.
Using json-simple to parse the JSON
This is the JSON file:
{
"entity": {
"id": "ppr20193060018",
"data": {
"relationships": {
"productpresentationtolot": [
{
"id": "",
"relTo": {
"id": "",
"data": {
"attributes": {
"rmsitemid": {
"values": [
{
"source": "internal",
"locale": "en-US",
"value": "2019306"
}
]
}
}
},
"type": "lot"
}
}
]
}
},
"type": "productpresentation"
}
}
Reading it using below code:
JSONParser parser = new JSONParser();
reader = new FileReader("path.json");
JSONArray rmsArray =(JSONArray) rmsitemid.get("values");
for(Object obj2:rmsArray)
{
JSONObject tempObj1=(JSONObject)obj2;
System.out.println(tempObj1.get("value"));
}
I'm able to print what is there in value(Key) i.e., 2019306 but i don't have any idea how can i replace it with some other value and it should change the value in JSON file also.
Any help appreciated!
