遍历方法代码如下：
import java.util.HashMap;
import java.util.Map;
public class App01 {
public static void main(String[] args) {
Map map1 = new HashMap();
map1.put("A", "ABC");
map1.put("B", "BCD");
map1.put("C", "CDE");
// 遍历
for(Map.Entry entry : map1.entrySet()) {
System.out.println(entry.getKey() + "->" + entry.getValue());
}
}
}
