There are no properties in Java, so it’s impossible there. You can have private getter and public setter methods, but not properties. It’s popular feature request https://youtrack.jetbrains.com/issue/KT-14663

I was thinking more of something like this:

public class Foo {
    private String bar;

    private String getBar() {
        return bar;
    }

    public void setBar(String bar) {
        this.bar = bar;
    }
}

But I was wrong, because you can’t use the property access syntax in Kotlin for this Java type.

I like the idea
