错误：找不到合适的方法put（String，int） [英] error: no suitable method found for put(String,int)

问题描述

编译时出错：

TreeMap <String, Long> myMap = new TreeMap <String, Long>();
//populate the map
myMap.put("preload_buffer_size", 1024);
myMap.put("net_buffer_length", 1024);
//etc...


error: no suitable method found for put(String,int)
    myMap.put("preload_buffer_size", 1024);
         ^
method TreeMap.put(String,Long) is not applicable
  (actual argument int cannot be converted to Long by method invocation conversion)
method AbstractMap.put(String,Long) is not applicable
  (actual argument int cannot be converted to Long by method invocation conversion)

我需要使用Long，而不是int
我真的不知道如何解决它，如果可以帮助我，我将不胜感激。

And I need to use Long, not int I don't really know how to resolve it, I would appreciate if you could help me with this.

推荐答案

myMap.put("preload_buffer_size", 1024L);
