Solution
Collections.sort(testList);
Collections.reverse(testList);
That will do what you want. Remember to import `Collections` though!
Here is the documentation for `Collections`.
Problem
I have a List of doubles in java and I want to sort ArrayList in descending order. Input ArrayList is as below: ``` List<Double> testList = new ArrayList(); testList.add(0.5); testList.add(0.2); testList.add(0.9); testList.add(0.1); testList.add(0.1); testList.add(0.1); testList.add(0.54); testList.add(0.71); testList.add(0.71); testList.add(0.71); testList.add(0.92); testList.add(0.12); testList.add(0.65); testList.add(0.34); testList.add(0.62); ``` The out put should be like this ``` 0.92 0.9 0.71 0.71 0.71 0.65 0.62 0.54 0.5 0.34 0.2 0.12 0.1 0.1 0.1 ```
