What is the maximum length of an array in Go, Java and C#?

What is the maximum length of an array that I can declare in Go, Java and C#? Does it relate to the maximum memory at runtime? Or do they have a standard?

Go array length is a value of type int, which is a 32 or 64 bit signed integer, depending on the compilation architecture (GOARCH), for example, 386 or amd64. It's also subject to any hardware or operating system memory size limits.

package main
import (
	"fmt"
	"runtime"
	"strconv"
)
func main() {
	fmt.Println("int is", strconv.IntSize, "bits on", runtime.GOARCH)
}

Output:
<pre>
int is 64 bits on amd64
</pre>
