Json to Double type JAVA

I am trying to get data from json to variables.One of variable is type of double but its getting 0.0 values.I tried some solution but they did'nt work.

This is my json: {"unitfactor":"0.1","unit":"N","canvassize":{"height":"302","width":"412"}

Code:

final JSONObject jObject = new JSONObject(fbeInput);
double mUnitFactor = jObject.getDouble("unitfactor");
String unit = jObject.getString("unit");

But mUnitFactor always gets 0.0 value. Even if i try to fetch unitfactor as string it did'nt show any value during debugging.

String mUnitFactor = jObject.getString("unitfactor");

"{"unitfactor":"0.1","unit":"N"}"

its because your unitfactor 0.1 is String in the making. change it to this:

"{"unitfactor":0.1,"unit":"N"}"

Remove the double quotation mark on 0.1.

or try to use the approach of @iNan:

double mUnitFactor = Double.parseDouble(fbeObject.getString("unitfactor"));

In this approach, you will first get the String unitfactor value, which is 0.1, and then you will parse it to Double using its wrapper class.

Since unitfactor is of type string, If you cannot change JSON then you can use

double mUnitFactor = Double.parseDouble(fbeObject.getString("unitfactor"))

There is no unit for varaibles in json. for string use "" , double inverted and for numeric like double,float, long directly assign value

in your case:

{"unitfactor": 0.1, "unit": "N"}
