Question on converting a new method into a property

[richardbl27]

Hi... I am relatively new to Java and object-oriented development. I've written the following Java / Groovy method which works correctly... I've been asked to convert this method into a property...

    boolean sortedDescending(columnId) {
        def doubleFormat = NumberFormat.instance
        def originalList = txnTable.column(columnId).collect { it.text() }
        def descendingSortedList = originalList.sort(false) { it ? -doubleFormat.parse(it) : Double.POSITIVE_INFINITY }
        return (descendingSortedList == originalList)
    }

Here is part of a class and my first incorrect attempt:

class TransactionTable extends Module {

    boolean sortedDescending

    void setSortedDescending(columnId) {
        def doubleFormat = NumberFormat.instance
        def originalList = txnTable.column(columnId).collect { it.text() }
        def descendingSortedList = originalList.sort(false) { it ? -doubleFormat.parse(it) : Double.POSITIVE_INFINITY }
        this.sortedDescending = (descendingSortedList == originalList)
    }

If you have any tips on how I can convert the above method into a property that would be wonderful.
All I really want to do is set sortedDescending to be true or false based on the comparison:
descendingSortedList == originalList
