How to make the application work with all devices?

Question

Android

There is a getCurrectHour() method, but it has been replaced with getHour() in newer versions. How to make the first one work on the old ones and the second one on the new ones?

if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {

}
