Returns a comparator that imposes the reverse of the natural ordering on a collection of objects that implement theComparableinterface. (The natural ordering is the ordering imposed by the objects' owncompareTomethod.) This enables a simple idiom for sorting (or maintaining) collections (or...
I have been testing out using delegates instead of reflection for some object sorting and it was working good for string properties, but if I try an Int (or DateTime) it fails and throws Error binding...Polymorphic default function argument Is there a way to avoid rewriting functions like ...

In this particular Java approach, we are going to construct and use the collections class to sort an array in the descending manner. First, we are going to apply the collection sort method for the process and array sort() function for further. It is a reverse sorting manner where we also...
stackoverflow.com/questions/7219597/sorting-songs-in-java,stackoverflow.com/questions/7200729/ Collections.reverse不排序。 它只是颠倒了列表元素的顺序。 因此,如果列表包含T, F, Z,它将包含Z, F, T。 您的代码截取器初始化了一个比较器,但没有执行任何操作。 如javadoc所述,此比较器仅在集合的元素实现Co...
