1 Overview of the StringBuffer1.1 StringBuffer If we need to stitch the strings, each stitch will build a new string object, which is time consuming and wasted space. And stringbuffer can solve this problem. StringBuffer is a thread-safe sequence of characters. 1.2 Construction methods Construction method: No-parameter construction method Public StringBuffer () Construction Method: Specifies the capacity of the string buffer Public StringBuffer (in

of the foreground, FID field is a to facilitate the design of the foreground query, the advantage of this design is that if the query, such as all products under the top-level menu, only need to match the fuzzy query prefix, you can query all the products, the design of the field is still a little small, IsLeaf is to determine whether it is a leaf node, belongsid the parent ID, Foreground code: Copy Code code as follows: Showtoolbar= "true" showcollapsebutton= "true" showfooter=

If you often need to modify a string, such as inserting, deleting, stitching, and so on, it is more appropriate to use Sringbuffer, because stringbuffer in string processing is not to generate new objects in memory because of the string class.The StringBuffer class has many of the same methods as the string class, which are functionally the same as in string, and StringBuffer is thread-safe and can be used conveniently in multithreaded programs. But the execution efficiency of the program is rel
