Another aspect of pointers is that they are the means to circumvent variable privacy. The only way one function can modify the rvalue of another function's local variable is if that function sends it the lvalue

Programs created with Java are portable because they are assembled in bytecode. It can be executed on any server that has Java Virtual Machine (JVM) installed. Unlike C++, objects created with Java do not have to reference external data. This means a Java application will continue running even...
So it's harder to do the kind of microperformance optimization with Java code that one can do in C. At the same time, the fact that the compilation is done at execution time means that the optimizer has far more information to work with than the C compiler does. It knows what classes...
The general contract of finalize is that it is invoked if and when the JavaTM virtual machine has determined that there is no longer any means by which this object can be accessed by any thread (that has not yet died), except as a result of an action taken by the finalization of some...

In the Java language, most method invocations arevirtual(potentially polymorphic), and are more frequently used than in C++. This means not only that method invocation performance is more dominant, but also that static compiler optimizations (especially global optimizations such as inlining) are much...
A reverse ordering means that the certificates are ordered from the most trusted CA (if present) to the target subject, whereas a forward ordering means that the certificates are ordered from the target subject to the most trusted CA. The order must be made known to the PKIXCertPathChecker ...
