Golang中的Java ArrayList <E>等效于什么？

In my particular use case, I would like to know how the following Java code would be implemented in Go -

class Channel {
    public String name;
    public Channel(){}
}

ArrayList<Channel> channels = new ArrayList<Channel>();

I've gotten started, and I think this would be the appropriate struct for Channel in Go -

struct Channel {
    name string
}

I just need to know how ArrayList would work in Go

Use a slice:

var channels []Channel  // an empty list
channels = append(channels, Channel{name:"some channel name"})

Also, your Channel declaration is slightly off, you need the 'type' keyword:

type Channel struct {
    name string
}

Here's a complete example: http://play.golang.org/p/HnQ30wOftb

For more info, see the slices article.

There's also the go tour (tour.golang.org) and the language spec (golang.org/ref/spec, see #Slice_types, #Slices, and #Appending_and_copying_slices).

Use slices.

For details on common slice idioms see the "Slice Tricks" wiki page.

This works

//make the object Channel
type Channel struct {
    name    string
}

// a empty list
var channels = []*Channel {}

//and finally add this object
channels = append(channels, Channel{name:"juan carlos anez mejias"})
