我正在嘗試在一個音節計數器上計算我輸入的字符串中的音節。這裏是說明。 -SyllableCounter用一個詞來計算音節
Syllables are really useful for a lot of things. They are defined according to the following rules involving
consonants (non-vowels) and vowels (a, e, i, o, u, y):
Starting y omitted:
(a) when words begin with y, we don’t count the starting y as a vowel. (we are
assuming there are no words that start with y followed immediately by a consonant)
Silent e omitted:
(a) when e is the last letter of a word, we’ll assume it is silent, unless the word is café or
entrée (words borrowed from French). (* we’ll ignore all other words to simplify)
For simplification, it may be best to create a new String without this silent e, before
checking for more syllables.
With the silent-e omitted, one-syllable units:
(a) have a single vowel.
(b) have two vowels that are the same letter in succession.
(c) have two vowels in immediate succession that are ei, ie, ea, ou, ey, ay, oy, uy, ai.
(d) have three vowels in immediate succession that are eau, iou (* yes, there are
exceptions to this that we are ignoring here).
With the silent-e omitted, two-syllable units:
(a) two vowels in immediate succession where the vowels are different letters not
following the rule above. For instance, oe, io, oi.
(b) three vowels in immediate succession not following the rule above where the last
vowel is not a silent e. For instance (「eye」) as in 「meyer.」
Generate a program called SyllableCounter that counts syllables in a word or sentence (maximum one
line). Assume the user will not use any punctuation. Pseudocode and a testing plan are required.
Do not print in main().
Sample output:
Please enter your word or sentence, followed by a carriage return.
Sally where are you going
Your entry has 7 syllables.
這裏是我當前的代碼（它編譯，但有一個的StringIndexOutOfBoundsException -
/*
* SyllableCounter.java
* Prints the number of syllables based on an inputed string
*
* Testing - What should work - All strings with letter characters
* What shouldn't work - Number values
