Sorting ArrayList

Question

Since I\'m just starting with JAVA, I\'m curious what is the best option for implementing sorting in JAVA (for ArrayLists). Below I provide my PHP code.

public i         


        

Answer 1

Try this solution:

public class SortArrayList{
    public static void main(String args[]){

        List unsortList = new ArrayList();

        unsortList.add("CCC");
        unsortList.add("111");
        unsortList.add("AAA");
        unsortList.add("BBB");
        unsortList.add("ccc");
        unsortList.add("bbb");
        unsortList.add("aaa");
        unsortList.add("333");
        unsortList.add("222");

        //before sort
        System.out.println("ArrayList is unsort");
        for(String temp: unsortList){
            System.out.println(temp);
        }

        //sort the list
        Collections.sort(unsortList);

        //after sorted
        System.out.println("ArrayList is sorted");
        for(String temp: unsortList){
            System.out.println(temp);
        }
    }
}
