java Map集合用stream流的方式遍历

Mapmap1=new HashMap<>();
        map1.put("aet","eat");
        map1.put("abt","bat");
        map1.put("cfv","vcf");
        map1.put("acd","cad");
        map1.entrySet().stream().forEach((Map.Entry entry)->{
            String key = entry.getKey();
            String value = entry.getValue();

        });
