数组中的跳跃问题

本文翻译自stackoverflow,by:王奎

问题:我有一个数组:

[1,2,3,6,7, 8, 9,20, 22]

我想让它对用户下面形式显示

Numbers 1 through 3, 6 through 9, 20, 22
以下是一个完整是程序:

/**

*/
public class ArrayTest{
public static void main(String[] args){
Integer[] A = {1, 2, 3, 6, 7, 8, 9, 20, 22};
System.out.print("Numbers ");
int start = 0, end;
while(start < A.length){
    System.out.print(A[start]);
    end = start;
    while(end + 1 < A.length && A[end + 1] == A[end] + 1)
        end++;
    System.out.print((end == start ? "":(" through " + A[end])) + ", ");
    start = end + 1;
}
	}
}
