我一直想有些事情出去，我已經打了，我想不通一個問題。GoLang：切片的清分片在指數函數的結果超出範圍
package main
import "fmt"
import "strconv"
func writeHello(i int,) {
fmt.Printf("hello, world "+strconv.Itoa(i)+"\n")
}
type SliceStruct struct {
data [][]int;
}
func (s SliceStruct) New() {
s.data=make([][]int,10);
}
func (s SliceStruct) AllocateSlice(i int) {
s.data[i]=make([]int,10);
}
func (s SliceStruct) setData(i int, j int, data int) {
s.data[i][j] = data;
}
func (s SliceStruct) getData(i int, j int) int {
return s.data[i][j]
}
func useSliceStruct(){
sliceStruct := SliceStruct{};
sliceStruct.New();
for i := 0; i < 10; i++ {
sliceStruct.AllocateSlice(i);
for j:=0; j<10; j++ {
sliceStruct.setData(i,j,i);
writeHello(sliceStruct.getData(i,j));
}
}
}
func dontUseSliceStruct(){
data:=make([][]int,10);
for i := 0; i < 10; i++ {
data[i]=make([]int,10);
for j:=0; j<10; j++ {
data[i][j] = i;
writeHello(data[i][j]);
}
}
}
func main() {
dontUseSliceStruct();
useSliceStruct();
}
當它到達功能useSliceStruct，代碼失敗在具有索引超出範圍的錯誤第一次調用AllocateSlice（）。
至於我可以告訴代碼兩種方法確實idential事情。那麼我錯過了什麼？
