單獨的數字和字母

Question

比方說，我有一個字符串，說"Hello123"，我怎麼能將它們分開成爲s[0] = "Hello", s[1] = "123"？我希望使用s.split()，但我不知道要在參數/參數中放置什麼。

你可以使用正則表達式：

String[] splitArray = subjectString.split(
    "(?x)     # verbose regex mode on     \n" + 
    "(?<=     # Assert that the previous character is... \n" + 
    " \\p{L}    # a letter         \n" + 
    ")      # and          \n" + 
    "(?=     # that the next character is...   \n" + 
    " \\p{N}    # a digit.         \n" + 
    ")      #           \n" + 
    "|      # Or          \n" + 
    "(?<=\\p{N})(?=\\p{L}) # vice versa");
