采纳答案by Ignacio Vazquez-Abrams
"Concatenate" joins two specific items together, whereas "append" adds what you specify to whatever may already be there.
“连接”将两个特定项目连接在一起，而“附加”将您指定的内容添加到可能已经存在的任何内容中。

When use Concator appendon two strings they both may give you same result when you output them
but the
main difference is on using concatenation new string object is created where as its not the same in case of StrinBuffer APPEND()
