not able to create Java Object from Json having double quote in value

I have same query. My JSON is as below.
String json="{ "credentials": { "password": "Password"123", "emailAddress": "skylineadmin#gmail.com" }, "clientTimeMs": 1582006455421, "callerRole": 0 }"
key = password and value is "Password"123" it contains " (double quote).. I am not able to create a java object from this json as it is invalidated.
Gson gson = new Gson();
gson.fromJson(json, PasswordResetDetails.java);
Above code snippet is not Working.

If you are doing this for learning / testing purpose all you need to do is escaping the double quote using :
String json="{ "credentials": { "password": "Password\"123", "emailAddress": "skylineadmin#gmail.com" }, "clientTimeMs": 1582006455421, "callerRole": 0 }"
If this is a real scenario then I would like to suggest to change the source in order to make sure it provides valid JSON.
There are countless possibilities to check if your JSON is valid (JSON linting), here's one.

I have a problem trying to parse a json file to JSON object
My JSON File is under the form :
{ "objectJSON": [
{
"attribute":"value",
"attribute":"value",
"attribute":"value",
"attributes" :{
"att1": "val1",
"att2":"val2",
"att3":"val3",
// more atts and vals may figure here !
}
},
{
"attribute":"value",
"attribute":"value",
"attribute":"value",
"attributes" :{
"att1": "val1",
"att2":"val2",
"att3":"val3",
// more atts and vals may figure here !
}
}
]
}
my problem is that the object "attributes" has an unknown number of arguments so I can not create a class for it , I thought about using a
map<String,String> attributes;
but I don't know how to parse it from the file especially that I want to keep my class "ObjectJSON" witch represents the root of my file.
I'm using gson of google
thanks in advance .

Using org.json library:
JSONObject jsonObj = new JSONObject("{\"phonetype\":\"N95\",\"cat\":\"WP\"}");

How to update .json attribute value converted into string?

I have a JSON file which I read from a location and converted it into string as below i.e. A string variable contains exact same JSON as printed below. For some testing purpose I needed it.
So the thing is that I want to update the value of key "MainId". How do I do that?
Here is mine JSON:
{
"Entity": {
"MainId":"XFG",
"AlternateIdentifiers" : [
{
"Type":{
"Abbreviation":"ReferenceNumber"
},
"Value":"abc"
}
]
}
}

Initialize a JSONObject , you have to import the json.org library , put the json in a string and then in the constructor of JSONObject.
So you can navigate the JSON through this new object.

how to create jsonObject according this structure?

Here is the structure of wanted JSON string
"1" : {
"Class': "group"
"text": "test1"
}
"2" : {
"Class': "group"
"text": "test1"
}
How can I create an jsonObject in Java that has this JSON representation?

You can either directly create the structure with Strings, or use a library that will create JSON objects in a more object oriented manner.
See https://stackoverflow.com/questions/338586/a-better-java-json-library for some discussion on various JSON libraries and their pros/cons.
You can also always go with JSON's official library: http://json.org/java/

Use JSONObject Class from net.sf.json.JSONObject like this:
JSONObject jsonObject=new JSONObject();
JSONObject childObject=new JSONObject();
childObject.put("class", "group");
childObject.put("text", "test1");
jsonObject.put("1", childObject);
jsonObject.put("2", childObject);
System.out.println(jsonObject.toString());

Converting JSON into java parse

I'm performing a query on my server which returns tree information in JSON format. Below
[{"leaf": 0, "context": {}, "text": "ABC-1-6-1", "expandable": 1, "id": "1.1.2.202.ABC-1-6-1", "allowChildren": 1}]
I was having play round with json-simple library and can parse it ok using JSONParser if can get the above info in String format i.e.
String jsonString = "{\"leaf\": 0, \"context\": {}, \"text\": \"1.1.2.202.ABC-1-6-1\", \"expandable\": 1, \"id\": \"1.1.2.202.ABC-1-6-1\", \"allowChildren\": 1}";
Any help would be great!

If you want to convert JSON to java then use gson. it is very simple.
Person fromJson = new Gson().fromJson(json, Person.class);// this will convert json to java object
fromJson.setAge(15);
fromJson.setName("json");
fromJson.setEmail("email#gmail.com");
fromJson.setMob("4657576876");
json = new Gson().toJson(fromJson);// this will convert java to json string like this {"name":"json","age":15,"email":"email#gmail.com","mob":"4657576876"}
