Comparable and Comparator both are the generic interfaces in Java used to compare the data elements of the objects. The Comparable interface is present in the java.lang package and the Comparator interface is present in the java.util package. The basic difference between the Comparable and Comparator interfaces is that the Comparable interface provides the single sorting sequence whereas, the  Comparator interface provides the multiple sorting sequences. There are some other differences … [Read more...]

Packages and Interfaces both acts as a container. The content in packages and interfaces can be used by the classes by importing and implementing it correspondingly. The basic difference between packages and interfaces is that a package contains a group of classes and interfaces whereas, an interface contains methods and fields. Let's study some other differences with the help of comparison chart. Content: Packages Vs Interfaces in Java Comparison Chart Definition Key … [Read more...]

Delegates and events both play an important role in the event-driven program. The delegates can refer to a method, and it is quite similar to the function pointer in C++. Events notify that some action has been performed. The basic difference between delegates and events is that delegates hold the reference of the methods and event provides a way to access that method using delegates. Content: Delegates Vs Events in C# Comparison Chart Definition Key Differences … [Read more...]

In C#, all the value types are derived from the class object. So, a reference variable of type object can refer to any other value type. C# introduces two methods to Boxing and Unboxing, which links value type to reference type. The basic difference between Boxing and Unboxing is that Boxing is the conversion of the value type to an object type whereas, on other hands, the term Unboxing refers to the conversion of the object type to the value type. Let us study the other differences between … [Read more...]

"Ref" and "Out" are the parameter modifiers used in C#. Using ref and out, you can pass any value type by its reference to any method. The reason of passing any value type by its reference introduces the main difference between the ref and out keyword. The ref keyword allows the called method to alter the content of the argument passed to it with ref keyword. The out keyword allows called method to return more than one value at a single call. Let's study the difference between ref and out … [Read more...]

Static and final both are the keywords used in Java. The static member can be accessed before the class object is created. Final has a different effect when applied to class, methods and variables. The main difference between a static and final keyword is that static is keyword is used to define the class member that can be used independently of any object of that class. Final keyword is used to declare, a constant variable, a method which can not be overridden and a class that can not be … [Read more...]

Interface and Abstract class both contribute to "incomplete type" in OOP. Sometimes we need a superclass to define "what to do" but, not "how to do", it's how to do part will be implemented by the derived class according to its need, "interface" provide a solution to this. Sometimes we need a superclass class that defines some generalised structure that can be implemented by derived classes and some specified structure that can be utilised by the derived classes, "abstract class" provides a … [Read more...]

The throw and throws are the keywords used in exception handling. The throw keyword is used to handover the instance of the exception created by the programmer to the JVM manually. The throws keyword used to handover the responsibility of handling the exception occurred in the method to the caller method. The basic difference between the throw and throws is that the throw keyword uses the exception object whereas the throws keyword uses the name of the exception classes. Content: throw Vs … [Read more...]

String and StringBuffer both are the classes which operate on strings. StringBuffer class is the peer class of the class String. The object of  String class is of fixed length. The object of the StringBuffer class is growable. The basic difference between String and StringBuffer is that the object of the "String" class is immutable. The object of the class "StringBuffer" mutable. Content: String Vs StringBuffer Comparison Chart Definition Key Differences Conclusion Comparison … [Read more...]

The words 'final, finally, and finalize' lies within the context of Java. Each one of them is provided a different functioning. The basic difference between final, finally, and finalize is that final is an access modifier, finally is a block and finalize is a method of an object class. There are some other differences between final, finally, and finalize which are discussed in the comparison chart. Content: Final Vs Finally Vs Finalize Comparison Chart Definition Key Differences … [Read more...]
