I\'m trying to create a PieChart in JavaFX, and I want to fill it with data from a HashMap.

Here\'s my code:

public Graph(HashM         


        

Answer 1

You seem to have imported the wrong "String" class ( com.org.apache.xpath.internal.operations.String) in your current file and the Data class expects the correct one (java.lang.String). Make sure your imports are correct (i.e. remove the import of the first type).

Also see this question, where the asker has run into a similar problem

Answer 2

this code snippet:

new PieChart.Data(entry.getKey(), entry.getValue());

entry.getKey() is not string

String s = entry.getKey();
new PieChart.Data(s, entry.getValue());

Try it
