When comparing the output of json.getString() to a string of same value i manually inputted into a json file, it's a false comparison.

println("-");
   println(jsonScene.getString("value"));
   println(jsonScene.getString("value") == "-");

Outputs

-
-
false

The same value is printed but when compared, it's false but should be true.

Remember in Processing (Java) you need to compare Strings using equals():

Compares two strings to see if they are the same. This method is necessary because it's not possible to compare strings using the equality operator (==). Returns true if the strings are the same and false if they are not.

For example:

println(jsonScene.getString("value").equals("-"));

CodePudding user response：

• Check the .charCodeAt(0) for both strings
• .trim() both of them before the comparison
• Check that typeof jsonScene.getString("value") === "string" (it could be an object with custom toString() defined)
