Java class, split with "," to convert a string to an array

String str = "A,b,c,";
string[] arr = Str.split (",");
System.out.println (arr.length);

The output length is 3,arr[0]= "a"; Arr[1]= "B"; Arr[2]= "C";

JS, to "," split, the string is converted to an array

var str = "A,b,c,";
var arr = Str.split (",");
Console.log (arr.length);

The output length is 4,arr[0]= "a"; Arr[1]= "B"; Arr[2]= "C"; arr[3]= "";

The last is an empty string.
