Strings2=“This is only a”;Strings3=“ simple”;Strings4=“ test”;Strings1=s2 + s3 + s4; 这时候,Java Compiler会规规矩矩的按照原来的方式去做,String的concatenation(即+)操作利用了StringBuilder(或StringBuffer)的append方法实现,此时,对于上述情况,若s2,s3,s4采用String定义,拼接时需要额外创建一个...
I would never make a statement so bold as "Use Stringbuilders to concatenate" without having a deeper understanding of the concatenation pattern. I tend to give advice like "Many users find Stringbuilders useful for their concatenation pattens, consider using them and measure to see if they hel...

For String manipulations in a non-multi threaded environment, we should use StringBuilder else use StringBuffer class. That’s all for a quick roundup of difference between String, StringBuffer, and StringBuilder. ...
