1func main() {2 result := new(Result)3The above code will not compile. The reason is that the Item method is defined in the result class. The result class is in the 1.go file. However, the other files do not know about the result class. If you want to use the Item method, you need to import the package in which the result lass is defined. The import statement is as follows:4import "1"5The import statement is as follows:6import "fmt"7The import statement is as follows:8import "fmt"9The import statement is used to import a package.
