Summary:
Immutable objects have a number of properties that
make working with them easier, including relaxed synchronization
requirements and the freedom to share and cache object references
without concern for data corruption. While immutability may not
necessarily make sense for all classes, ...

The benefits of garbage collection are indisputable -- increased
reliability, decoupling of memory management from class interface
design, and less developer time spent chasing memory management errors.
The well-known problems of dangling pointers and memory leaks simply do
not occur in Java prog ...

In the early days of Java technology, allocating objects got a
pretty bad rap. There were lots of articles (including some by this
author) advising developers to avoid creating temporary objects
unnecessarily because allocation (and the corresponding
garbage-collection overhead) was expensive. Wh ...

Summary:
Every Java object has a hashCode()
and an equals()
method. Many classes override the default implementations of these
methods to provide a higher degree of semantic comparability between
object instances. In this installment of Java theory and practice
, Java developer Brian Goetz s ...
