在Golang中初始化新类(将Java转换为Golang)

I am trying to convert this java to golang and now I have this bug. I don't know why this bug is showing up.

here is the java code:

     ArrayList<Cell> path; // path does not repeat first cell
    String name;
    static int count = 0;

    public Path() {
        this.path = new ArrayList<>();
        this.name = "P" + (++this.count);
    }

    public Path(Path op) {
        this.path = new ArrayList<>();
        this.name = op.name;
        path.addAll((op.path));
    }

Here is what i wrote

    type Path struct {
    name  string
    count int
    path  []Cell
}

func NewPath() (p *Path) {
    p = new(Path)
    p.path = []Cell{}
    p.count = 0
    p.name = "P" + strconv.Itoa(1+p.count)
    return
}

func NewPath(op Path) (p *Path) {
    p = new(Path)
    p.path = []Cell{}
    p.count = 0
    p.name = op.name
    p.path = append(p.path, op.path)
    return
}

The go system said I am wrong in term of redeclaring NewPath, with the error:

prog.go:21:6: NewPath redeclared in this block

How can I debug it?
