如何遍历数组

package collections;
  
import java.util.HashMap;
  
public class HashMapDemo {
  
    public static void main(String[] args) {
        HashMap<String, String> map = new HashMap<String, String>();
        // 添加内容，内容以key/value方式填入
        map.put("湘南IT培训", "https://www.0735it.com/");
        map.put("google","https://www.google.com/");
        map.put("利永贞网","https://www.liyongzhen.com");
          
        // java 5 for 方式遍历;后进先出来
        for(String key:map.keySet()) {
            System.out.printf("key %s;\nvalue %s\n",key,map.get(key));
        }
          
        // java 8 forEach 方式遍历
        map.entrySet().forEach(e->              
                System.out.printf("key %s;\nvalue %s\n",e.getKey(),e.getValue())       
        );
    }
  
}
