節錄如下：
The Java language provides special support for the string concatenation operator ( + ), and for conversion of other objects to strings. String concatenation is implemented through the StringBuilder(or StringBuffer) class and its append method. String conversions are implemented through the method toString, defined byObject and inherited by all classes in Java. For additional information on string concatenation and conversion, see Gosling, Joy, and Steele, The Java Language Specification.
String s = x + y + z;
等同於: String s = new StringBuilder(x).append(y).append(z);

但現在回頭看看~兩年的時間~好像沒有太長!
現在想想當初念研究所的原因~是因為逃避面對現實嗎??

當物件不在被參照變數(reference variable)參考(refer)時，他會被認為是不再使用的garbage。
