method below retrieves seven days and return short name of days in List Array in Kotlin though, you can just reformat then in Java format, just presenting idea how Calendar can return short name

private fun getDayDisplayName():List{
        val calendar = Calendar.getInstance()
        val dates= mutableListOf()
        dates.clear()
        val s=   calendar.getDisplayName(DAY_OF_WEEK, SHORT, Locale.US)
        dates.add(s)
        for(i in 0..5){
            calendar.roll( Calendar.DATE, -1)
            dates.add(calendar.getDisplayName(DAY_OF_WEEK, SHORT, Locale.US))
        }
        return dates.toList()
    }

out put results like

I/System.out: Wed
    Tue
    Mon
    Sun
I/System.out: Sat
    Fri
    Thu
