How to do it...

1. Declare the ColoredText class:

data class ColoredText@JvmOverloadsconstructor(        var text: String = "",        var color: Color = defaultColor) {    companion object {        @JvmField        val defaultColor = Color.BLUE    }}

2. Implement a static JVM method inside the companion object:

data class ColoredText@JvmOverloadsconstructor(        var text: String = "",        var color: Color = defaultColor) {    companion object {        @JvmField        val defaultColor = Color.BLUE        @JvmStatic        fun processText(text: String): String =                with(text) {                    toLowerCase().trim().capitalize()                }    }}

3. Add a member function that enables you to print the text property to the console:

data class ColoredText@JvmOverloadsconstructor(        var text: String = "",        var color: Color = defaultColor) {    fun printToConsole() ...
