Map集合遍历的两种方式 java

public static void main(String[] args) { Map map = new HashMap(); map.put("黄海燕","何沁秋"); map.put("马月平","麻将"); map.put("杨悦","李阳");

方法一：根据KeySet方法获取主键集合，然后根据主键找到对应的值进行遍历

Set keySet = map.keySet(); //for(String i :keySet){ //String value = https://www.it610.com/article/map.get(i); //System.out.println(i+","+value); //}

【Map集合遍历的两种方式】方式2：根据entrySet()方法获取map，创建set集合对象，然后根据集合对象获取对应的主键和值

Set entrySet = map.entrySet(); for (Map.Entry me:entrySet){ String key = me.getKey(); String value = https://www.it610.com/article/me.getValue(); System.out.println(key+","+value); }
