java中给map赋值吗_java map赋值报错

Map headers = new HashMap();

headers=new unitting().headers();package utils;

import java.util.HashMap;

import java.util.Map;

public class unitting {

public long khronos = ((int) (System.currentTimeMillis() / 1000));

public Map headers()

{

Map Headers = new HashMap();

Headers.put("authority","webcast.amemv.com");

Headers.put("scheme","https");

Headers.put("accept-encoding: ","gizp");

Headers.put("response-format","protobuf");

Headers.put("passport-sdk-version","18");

Headers.put("sdk-version","2");

Headers.put("cookie","odin_tt=005d7559c7953e970d3938a55d005402cdcb53ac5bf2094986b8ebcdf37b0894b211efff588e8fd187251c4fe3f90f05a73b9a3495327fc3823946582a0542f3; install_id=369400941537578");

Headers.put("x-khronos",khronos);

Headers.put("user-agent","okhttp/3.10.0.1");

return Headers;

}

}

headers=new unitting().headers(); 这里直接map 复制报错 这是为啥
