Handled an exception for a previously written Java applet

Prior to the use of Java 0-99 of the number and translation between English, the input number will be translated into English, input English will be translated into numbers, such as input 56 output fiftysix input Fiftysix output 56,

Found that this will be an exception, when the input does not conform to the format, such as English and digital mixed, or input punctuation will be reported numberformatexception exception, and now catch the exception, by the way

Input out of bounds also added an exception, such as input 100 times "input out of bounds!" "。
