Using JSON StringOf with Non-String Members

See more JSON Examples

If a JSON member is a boolean, integer, or null, using StringOf will return its string representation. Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    //  Create JSON with members of different data types.
    CkJsonObject json = new CkJsonObject();

    json.UpdateInt("a",123);
    json.UpdateBool("b",true);
    json.UpdateNull("c");

    json.put_EmitCompact(false);
    System.out.println(json.emit());

    //  Resulting JSON:
    //  {
    //    "a": 123,
    //    "b": true,
    //    "c": null
    //  }

    String a = json.stringOf("a");
    System.out.println(a);

    String b = json.stringOf("b");
    System.out.println(b);

    String c = json.stringOf("c");
    System.out.println(c);

    //  Output

    //  123
    //  true
    //  null

    //  If you want to get the integer, boolean, or null value
    //  you need to use the methods matching the data type
    int ival = json.IntOf("a");
    boolean bval = json.BoolOf("b");
    boolean hasNull = json.IsNullOf("c");
  }
