java字典排序

❶ 如何对Map进行字典排序java

//根据 Map的key进行字典排序
Map<String, String> parameterMap = new HashMap<String, String>();
List<Map.Entry<String,String>> list = new ArrayList<Map.Entry<String,String>>(parameterMap.entrySet());
Collections.sort(list,new Comparator<Map.Entry<String,String>>() {
//升序排序
public int compare(Entry<String, String> o1,
Entry<String, String> o2) {
return o1.getKey().compareTo(o2.getKey());
}

});

list.set(i,list.get(j));

}
}

❸ JAVA按着字典顺序排序

如果同时有 new String[] { "ye", "yel", "yellow" };你的排序是ye,yel,yellow
但是如果new String[] { "yel", "ye", "yellow" };排序就变成 排序后:yel ye yellow

❹ Java怎么按照汉字字典顺序给字符串排序
