java中的list、map比较

Question

    我有一个（Map<路名,对应的实体类>）还有一个（List<Map<企业标识,住所>>）我想根据map里面的路名
和list里面的住所进行比较得到符合条件的List<Map<企业标识，住所>>
    比如map中有个路名：舟山路
    我希望得到list里面的住所包含舟山路的数据  比如：住所舟山路328号

Answer 2

不难啊map里面或者舟山路 然后循环每个List list.get(i)是一个Map 然后获取他的value 是否包含前面的舟山路  不久OK？

Answer 3

代码如下：
请仔细分析代码，debug理解。我也是花挺长时间写的。所以一定要有耐心、要细心。
package com.snow.test;import java.util.ArrayList;
import java.util.Collection;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.Set;public class CompareAddress {
public static void main(String[] args) {
Map<String, String> m1 = new HashMap<String, String>();
m1.put("舟山路", "舟山路1");

List<Map<String, String>> list = new ArrayList<Map<String, String>>();
Map<String, String> m2 = new HashMap<String, String>();
m2.put("百度", "舟山路328号");
m2.put("CSDN", "舟山路220室");
m2.put("谷歌", "舟山路224号");
m2.put("腾讯", "世纪大道舟山路217号");
m2.put("IBM", "西安");
list.add(m2);

Collection<String> c = m1.keySet();
String keyWord = null;
for (Iterator<String> iterator = c.iterator(); iterator.hasNext();) {
//System.out.println(iterator.next());
keyWord = iterator.next();
}
for(Map<String,String> temp : list){
Set<Map.Entry<String,String>> set = temp.entrySet();
for (Iterator<Map.Entry<String, String>> iterator = set.iterator(); iterator.hasNext();) {
Map.Entry<String, String> entry = (Map.Entry<String, String>) iterator.next();
if(entry.getValue().contains(keyWord)) {
System.out.println(entry.getValue());
}
// System.out.println(entry.getValue());
}
}

}
}
