如何在Java中使用Collections.sort（）？

使用此方法Collections.sort（List，Comparator）。实施比较器并将其传递给

Collections.sort().

class RecipeCompare implements Comparator<Recipe> {    @Override    public int compare(Recipe o1, Recipe o2) {        // write comparison logic here like below , it's just a sample        return o1.getID().compareTo(o2.getID());    }}

然后使用

Comparator

Collections.sort(recipes,new RecipeCompare());
