String buffers support mutable strings. Because String objects are immutable they can be shared. For example: String str = "abc"; is equivalent to: char data[] = {'a', 'b', 'c'}; * String str = new String(data); 从上面我们可以知道每次对String对象的赋值,都是已经改变了String指向的...

For example, if z refers to a string buffer object whose current contents are "start", then the method call z.append("le") would cause the string buffer to contain "startle", whereas z.insert(4, "le") would alter the string buffer to contain "starlet". In general, if sb refers ...
