原标题:android HashMap warning

Im an Anders noob, from objC,

我有一个非常棘手的问题(项目工作罚款和伐木预期结果)。

package com.orchard.hasho;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import android.util.Log;

public class Numa {

public static void main() {


    Map mMap = new HashMap(); //crea nuevo HashMap
    mMap.put("llave 1", "la llave uno"); //le mete cosas al hashMap
    mMap.put("llave 2", "la llave dos");
    mMap.put("llave 3", "la llave tres");
    mMap.put("llave 4", "la llave cuatro");

    Iterator iter = mMap.entrySet().iterator();

    while (iter.hasNext()) {
         Map.Entry menEntry = (Map.Entry) iter.next();

         Log.d("msg", "key:"+menEntry.getKey() +" value:"+menEntry.getValue());
    }


}
}

最新代码一

But I get many warnings,

ie,Map mMap = new HashMap(); press:

我已注意到,在我创建地图时,汽车完工使我可以选择<代码>。 Map<K, V>

摘自我的 i dont see this <Key, Value>? syntax s when establishing the Hashmap or populationing it?

因此,这些警告是什么,为什么汽车公司给我选择了<条码>Map<K, V>,以及如何确定警告? 感谢!

最佳回答

由于java 1.5大体化,你可以具体说明这一地图将包含哪些类型的物体,如你想要将“强硬”用作关键和价值,请使用:

Map<String, String> mMap = new HashMap<String,String>();
