java 应用subList List分割_J2EE

java 使用subList List分割
list中有1000条数据，把1000分为20集合，每个分别打印出来，请教简单例子实现功能？

Java code

public static void main(String[] args) {        int count = 1000;        int index = 0;        List<Integer> list = new ArrayList<Integer>();        for (int i = 0; i < count; i++) {            list.add(i+1);        }        for (int i = 0; i < 20; i++) {            List<Integer> temp = list.subList(index, index+count/20);            index += count/20;            System.out.println("the data of list " + (i + 1) + "===========>");            for (int j = 0; j < temp.size(); j++) {                System.out.println(temp.get(j));            }        }    }

Java codeList<Integer> list=new ArrayList<Integer>();        for(int i=1;i<1001;i++)            list.add(i);        int count=list.size()/20;        for(int i=0;i<20;i++){            List<Integer> subList= list.subList(i*count,count*(i+1));            System.out.println(subList);        }
