一道算法问题！求解

[shaot399]

我有一个list,list的size假设为108,现在我想把list分成十个子list,子list的长度分别为
11,11,11,11,11,11,11,11,11,9
大家帮忙想想怎么解决！

List是动态加载的 不固定size
如果要分 那就是把目标元素分散到十个list中去就完了

boolean java.util.List.add(E o)

你可以麻烦点啊
从里面取出来放到相应的list中，然后再把各个list加到一个list里面啊
List a1=new ArrayList();
List a2=new ArrayLIst();
......

[lsc1202001]

list1 = list.subList(0, 11);
list2 = list.subList(11, 22);
....

List 有个方法...

list.subList(0, 11);
你在加个循环 和长度判断就可以了

[code=Java]import java.util.ArrayList;
import java.util.List;

class Test{
	public static void main(String[] args) {
		List list = new ArrayList();
		for (int i = 0; i < 108; i++) {
			list.add(""+i);
		}
		List[] result = split(list, 11);
		for (int i = 0; i < result.length; i++) {
			System.out.println(i+1 + "=" + result[i].size());
		}
	}

	public static List[] split(final List list, final int standardSize) {
		int listSize = list.size();
		int left = listSize % standardSize;
		int num = listSize / standardSize + (left == 0 ? 0 : 1);
		List[] result = new List[num];
		int i = 0;
		for (i = 0; i < num-1; i++) {
			result[i] = list.subList(i*standardSize, (i+1)*standardSize);
		}
		result[i] = list.subList(i*standardSize, list.size());
		
		return result;
	}	
}

sublist 貌似很方便

谢了，自己也实现了，不过也要给分！哈哈
