Java代码如下：

package Test01;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;public class Test06 {	/**	 * @param args	 */	public static void main(String[] args) {		// TODO Auto-generated method stub		a();		b();	}		@SuppressWarnings({ "rawtypes", "unchecked" })	public static void a(){		List list = new ArrayList();		for (int i = 0; i < 10; i++) {		list.add(i);		System.out.print(list.get(i)+" ");		}		System.out.println();				Map map = new HashMap();		for (int i = 0; i < list.size(); i++) {		map.put(i, list.get(i));		System.out.print(map.get(i));		}		System.out.println();		System.out.println(map);	}		@SuppressWarnings({ "rawtypes", "unchecked" })	public static void b(){		List list = new ArrayList();				list.add("河南");		list.add("郑州");		list.add("登封");		list.add("开封");		list.add("上海");				System.out.print(list);				System.out.println();				Map map = new HashMap();		for (int i = 0; i < list.size(); i++) {		map.put(i, list.get(i));		System.out.print(map.get(i));		}		System.out.println();		System.out.println(map);	}}

 

代码运行后效果如下:
