[java] How to convert minutes to Hours and minutes (hh:mm) in java

(In Kotlin) If you are going to put the answer into a TextView or something you can instead use a string resource:

<string name="time">%02d:%02d</string>

And then you can use this String resource to then set the text at run time using:

private fun setTime(time: Int) {
    val hour = time / 60
    val min = time % 60
    main_time.text = getString(R.string.time, hour, min)
}
