Excelsior: [Java] 淺談call by value 和call by reference
[Java] 淺談call by value 和call by reference. 在C++ 中, call-by-value 意味著把變數的值複製一份傳進函數; 而call-by-reference 則意味著把變數的alias (用&var 或者指標) 傳進函數當中。 因此，在C++ 中我是這麼理解的，在函數內部改變call-by-value 傳入的參數並不會影響外部變數，因為傳進來... http://brownydev.blogspot.com 074-Java參考值呼叫(Call by Reference) - 程鼎元(Ding-Yuan Cheng)

事實上，C++的參考，比較常用的場合是在呼叫函式時，傳遞參數給函式的時候，稱為call by reference。在C++的標準函式庫中，很常見到這樣的作法，如srting類別的compare函式：. int string::compare( const string& str ) const;. 這樣做的好處，與C的傳址呼叫(call by address)是一樣的，就是避免傳遞大型資... http://myleslittlewolf.pixnet. Is Java "pass-by-reference" or "pass-by-value"? - Stack Overflow
