Array.sort()
1. Arrays.sort(int[] a): 从大到小的排序
2. Arrays.sort(int[] a, int fromIndex, int toIndex): 从大到小的排序
3. public static<T> void sort(T[] a, int fromIndex, int toIndex, Comparator<? super T> c)
example for the last method:
Integer[] a = {9,8,7,2,3,4,1,0,6,5};
Comparator cmp = new MyComparator();
Arrays.sort(a, cmp);
Class MyComparator implements Comparator<Integer>{
@Override
public int compare(Integer o1, Integer o2){
if(o1 < o2) return 1;
else if (o1 > o2) return -1;
else return 0;
}
}
