Inheritance is another of the basic OOPs concepts in Java and the most powerful feature in which one class shares structure and behavior defined in one or more classes. The medium of obtaining a new class from an old class is defined as inheritance or derivation. It is the relationship among...
The compiler allocates much more than 32 bits of heap to this object. ints are 32 bits long in java but every object has headers. The size of these headers differs in 32bit and 64bit and in different VMs. In a 32bit virtual machine each of these header fields are one word or 4 b...
Using this feature of OOP, a new class, known as the “derived class” or “child class,” can inherit properties and characteristics from an existing class called the “base class” or “parent class.” This process allows the derived class to inherit all the features of the base class ...

It is a feature in the Java Virtual Machine (JVM) that allows the JVM to use compressed pointers for object references, reducing memory usage. When running a Java application, including NiFi, with CompressedOops enabled, the JVM optimiz...
