It happens because they are located at different locations in a heap. Besides being two objects, there are no significant differences in both objects. If we use the concept of String Interning, we only create a single object let us assume it asstrObj, and now it contains the content of th...
The above code creates two objects. One object is created in String constant pool and the other is created on the heap in non-pool area. 79. What is String interning?字符串的驻留 String interning refers to the concept of using only one copy of a distinct String value that is Immutable....

[英]Bare-bones, unsafe, fast string buffer. No thread-safety, no parameter range checking, exposed fields. Note that in typical applications, thread-safety of a StringBuffer is a somewhat dubious concept in any case. Note that Stree and DTM used a single FastStringBuffer as a string pool,...
Note that in typical applications, thread-safety of a StringBuffer is a somewhat dubious concept in any case. Note that Stree and DTM used a single FastStringBuffer as a string pool, by recording start and length indices within this single buffer. This minimizes he...
