Java 打印一个带有 ", "符号的整个数组？

Question

System.out.print("Please select a game: ");
for (String s : gamesArray) {       
    System.out.print(s + ", "); 
}

输出:

Please select a game: spin, tof, Press any key to exit...

我排除的输出:

Please select a game: spin, tofPress any key to exit...

为什么在最后一个数组项之后添加另一个','？ 我该如何预防？

为什么不直接调用Arrays#toString(array):

System.out.print("Please select a game: %s%n", 
                  Arrays.toString(gamesArray).replaceAll("(^\\[)|(\\]$)", ""));

或避免使用正则表达式:

String tmp = Arrays.toString(gamesArray);
System.out.print("Please select a game: %s%n", tmp.substring(1, tmp.length()-1));
