Go Language Learning: Creating a dynamic array being given the "non-constant array bound"

package main

//正确
func createArray2(size int) []int{
	return make([]int, size)
}

//错误
func createArray(size int) []int{
	return [size]int
}

func main(){
	createArray(5)
}

Go with a slice slice to construct a dynamic array. This is different with java:

public class Test {
    //正确
	private static int[] createArray(int size){
		return new int[size];
	}
	public static void main(String[] args) {
		int[] a = createArray(5);
		System.out.println(a[4]);
	}
}
