Character.forDigit介绍
[英]Returns the character which represents the specified digit in the specified radix. The radix must be between MIN_RADIX and MAX_RADIX inclusive; digit must not be negative and smaller than radix. If any of these conditions does not hold, 0 is returned.
[中]返回表示指定基数中指定数字的字符。基数必须介于最小基数和最大基数之间（包括最小基数和最大基数）；数字不得为负数且小于基数。如果这些条件中的任何一个不成立，则返回0。
