String list in java

Question

I have a very simple question in java

below is my code I am trying to declare a string as given but its showing error in java.

import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;

public class Testjava {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

         // one easy string, one that's a little bit harder
        String[] testStrings = {"datefrom":"2018-03-19T23:59:59Z","dateto":"2018-03-22T23:59:59Z", "name" : ["flow"]};

          String encodedString;
          for (String s : testStrings)
          {
        try {
            encodedString = URLEncoder.encode(s, "UTF-8");

          System.out.format("'%s'\n", encodedString);

        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }




    }
}

Can someone tell me how to declare this string value?

What is it that you want? A string or an array of strings? It's not clear. — Robert Kock, Sep 06 '19 at 10:58
You are trying to declare a JSON part as a String array; this is not possible as you do it. — Uwe Allner, Sep 06 '19 at 10:58
please see the updated one.String[] testStrings is what i need to pass. where its erroring bec of the special chara. — TTT, Sep 06 '19 at 10:59
This does not compile. That is not a valid array initializer. And which one is that "special chara"? — f1sh, Sep 06 '19 at 11:00
yes its not even cmpiling... see i want to encode the value given in testStrings .. how i can acheive this :( — TTT, Sep 06 '19 at 11:01
You seem to be confusing JavaScript syntax with Java syntax. See https://stackoverflow.com/questions/1938101/how-to-initialize-an-array-in-java/1938302. — Konrad Höffner, Sep 06 '19 at 11:04
@TTT I think you confuse "encoding" with "valid java syntax" — f1sh, Sep 06 '19 at 11:09
By the way, you might want to learn about handling a time range using the Half-Open approach where the beginning is *inclusive* while the ending is *exclusive*. — Basil Bourque, Sep 06 '19 at 15:03

Your String array is incorrect. You need to escape the " characters.

Try:

 String[] testStrings = {"datefrom\":\"2018-03-19T23:59:59Z","dateto'\":\"2018-03-22T23:59:59Z", "name\" : [\"flow\"]"};
