有空可以看看，

不知能不能超越JAVA的作法。

hello.go

package mainimport "fmt"func main() {    s := "hello"    m := " world"    a := s + m    b := [...]int{4, 5, 6, 7,8}    var ar = [10]byte {'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'}    var c, d []byte    c = ar[2:5]    d = ar[3:5]    numbers := make(map[string] int)    numbers["one"] = 1    numbers["two"] = 10    numbers["three"] = 3    x := 12    if x > 10 {        fmt.Println("x is greater than 10")    } else {        fmt.Println("x is less than 10")    }    sum := 0;    for index:=0; index<10;index++ {        sum += index    }    fmt.Println("sum is equeal to ", sum)    fmt.Printf("%d\n", numbers["three"])    fmt.Printf("%d\n", c)    fmt.Printf("%d\n", d)    fmt.Printf("%s\n", a)    fmt.Printf("The first element is %d\n", b[0])}
