I have a Java Rest API @PUT. Which is receiving the json data as shown in below format
["name1,scope1,value1","name2,scope2,value2"]
I am getting this value in my Java API method as
(String someList)
someList will contain ["name1,scope1,value1","name2,scope2,value2"]
How to get these values ("name1,scope1,value1" and "name2,scope2,value2") in String array?
Using the org.json package, this would do (assuming response as String in responseString):
JSONArray myJSON = new JSONArray(responseString);
String[] myValues = new String[myJSON.length];
for(int i=0; i<myValues.length; i++) {
myValues[i] = myJSON.getString(i);
}
If you then want to split up the strings in myValues[] using ',' as a separator, you can do:
String[] innerArray = myValues[i].split(",");
An example JSON code :
import org.json.simple.JSONObject;
import org.json.simple.JSONArray;
import org.json.simple.parser.ParseException;
import org.json.simple.parser.JSONParser;
class JsonDecodeDemo
{
public static void main(String[] args)
{
JSONParser parser=new JSONParser();
String s = "[0,{\"1\":{\"2\":{\"3\":{\"4\":[5,{\"6\":7}]}}}}]";
System.out.println("s = " + s);
try{
Object obj = parser.parse(s);
JSONArray array = (JSONArray)obj;
System.out.println("The 2nd element of array");
System.out.println(array.get(1));
System.out.println();
JSONObject obj2 = (JSONObject)array.get(1);
System.out.println("Field \"1\"");
System.out.println(obj2.get("1"));
s = "{}";
obj = parser.parse(s);
System.out.println(obj);
s= "[5,]";
obj = parser.parse(s);
System.out.println(obj);
s= "[5,,2]";
obj = parser.parse(s);
System.out.println(obj);
}catch(ParseException pe){
System.out.println("position: " + pe.getPosition());
System.out.println(pe);
}
}
}
You can refer to this.
You could put the parts into an array of String with just one line:
String[] parts = someList.replaceAll("^\\[\"|\"\\]$", "").split("\",\"");
The call to replaceAll() strips off the leading and trailing JSON adornment and what's left is split on what appears between the target parts, ie ","
Note that due to the flexible nature of valid json, it would be safer to use a JSON library than this "string based" approach. Use this only if you can't use a json library.
