What are the differences between gc methods of System and Runtime Classes in Java?
There is actually no difference between System.gc() and Runtime.gc(). They both essentially invoke the JVM's Garbage Collection operation.
The System.gc() is a static method so it's a little bit more convenient to use. The call System.gc() is effectively equivalent to the call:
Runtime.getRuntime().gc()
What else can I help you with?
Addition of methods into object at runtime?
Of course not.
What is difference in use between interfaces and abstract classes in java?
While neither abstract classes nor interfaces can be instantiated in Java, you can implement methods in abstract classes. Interfaces can only define methods; no code beyond a method header is allowed.
What are the differences between old and new irrigation methods?
t are the difference between old and new irrigation method
Why run time polymorphism is dynamic and compile time polymorphism is static?
The simple answer is that compile-time polymorphism occurs at compile time while runtime polymorphism occurs at runtime. The actual answer is that compile-time polymorphism results in the compiler generating source code on your behalf while runtime polymorphism relies on function pointers or virtual methods to determine the next instruction at runtime. Compile-time polymorphism therefore applies to template functions and classes since that is the only way the compiler can generate source code on your behalf. To achieve this, the runtime type for the template parameters must be fully-defined at compile time, even if those types have runtime polymorphic characteristics of their own. Runtime polymorphism applies to virtual methods and function pointers, both of which can be used to dynamically alter the execution path of your program. Virtual methods are made possible through virtual tables, which are essentially just arrays of function pointers. Each runtime type that derives from a base class with virtual methods provides its own virtual table, thus the runtime type determines which specific function overrides will be invoked at runtime, even if the runtime type cannot be determined at compile time. In this way you can generalise your code to work with the base type but still get the expected polymorphic behaviour whenever a derived type is passed instead.
Who invoke main function in java?
The Java Runtime Environment invokes main methods.
Addition of methods into object at runtime?
Of course not.
What are the differences between Montessori and kindergarten methods?
No difference
What is binding in c plus plus?
Binding refers to classes and their member methods. A class that has no virtual methods can simply be bound to all its methods at compile time. This is known as static binding. However classes with virtual functions require special handling as they can be overridden by derived classes. If the derived class cannot be determined at compile time, then its overridden methods are dynamically bound at runtime, using the virtual table (or v-table) to determine which version of a method must be called.
What is difference in use between interfaces and abstract classes in java?
While neither abstract classes nor interfaces can be instantiated in Java, you can implement methods in abstract classes. Interfaces can only define methods; no code beyond a method header is allowed.
What is the difference between properties and methods in qtp?
property is like variable (can able to set and get value at runtime) but method is like a function which will return the value at runtime so the only different is property will hold the value untill the new value will set into that.
What are the differences between methodology and methods?
method is the way to do something and methodology is the study of how to do something
What are the differences between old and new irrigation methods?
t are the difference between old and new irrigation method

What are the similarities and differences between evaporation and distillation?
They are both methods which use heat to separate mixtures.
What is Difference between C structers and classes?
through classes we can create objects and we can implemented businessmathods. in case of structres we can create streuctre variables but not methods this is the major difference
How we use reflection?
Reflection in programming allows you to inspect and manipulate class, methods, fields, and annotations at runtime. It can be used for tasks like implementing dynamic loading of classes, examining and modifying objects, and invoking methods dynamically. Reflection provides flexibility but can also lead to performance overhead and security risks if not used carefully.
