从另一个包和文件golang导入结构体

I have a problem trying to import a type from another package and file. The struct that I'm trying to import is the one underneath.

type PriorityQueue []*Item

type Item struct {
   value string
   priority int   
   index int 
}

If I would put the PriorityQueue alongside with all of its methods in the same file I'd declare it with

pq:= &PriorityQueue{}

I've been searching the internet like a madman for an answer on this simple question but I have not found an answer. I usually program in java and import classes is so elementary.

In Go you don't import types or functions, you import packages (see Spec: Import declarations).

An example import declaration:

import "container/list"

packagename.Identifiername

var mylist *list.List = list.New()

// Or simply:
l := list.New()

There are some tricks in import declaration, for example by doing:

import m "container/list"

"m.Identifiername"

l := m.New()

Also by doing:

import . "container/list"

You can leave out the package name completely:

l := New()

But only use these "in emergency" or when there are name collisions (which are rare).
