What is meaning of root element. why Z is not root element??<br />
System.out.println(t)//com<wbr />es [A,B,Z} right not [Z,B,A]<br />
how to get custom sorting like Z B A<br />
<br />
why StringBuffer does not support default natural sorting. How to sort String Buffer objects.<br />
<br />
obj1.compareTo(obj2)//obj2<wbr /> is already present element in tree set and obj1 is new element being added??<br />
<br />
please advise

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.

Java EE

A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.
